EXC_BAD_ACCESS (SIGSEGV) with Intel SheepShaver 2.5 (Dec 2022) build on Ventura (macOS 13.3.1 (a) (22E772610a))

[nandrews]

Howdy! Longtime user, first time complainer.

I use SheepShaver on a variety of macOS machines, both Intel and Apple Silicon. I've only run up against this issue on my 2015 Retina MBP, running Ventura using OpenCore Legacy Patcher.

Since the latest Ventura update, SheepShaver throws a segfault (details below), using any prefs file or ROM version. I've tried a variety of known good prefs and known good ROMs, and clean installations, to no avail.

I'm willing to accept that this has something to do with OpenCore weirdness; that said, I'm running Ventura via OCLP on two other Macs on which the Dec 22 2.5 build runs without an issue, the only difference being that the offending machine is the only one updated with the most recent Ventura security patches.

Any help would be most appreciated. I have quite a stable of vintage Macs and am working on a documentation archive for same, so the ability to extract data from HyperCard stacks, DocViewer tomes, and early FileMaker databases is rather mission-critical.

I'm currently working on compiling it from source under the most current Xcode build, and will revise this post if that yields running code.

Any help in the meantime would be deeply appreciated.

1. If you did not do that already, enable "Ignore Illegal Memory Accesses" in SheepShaver Preferences/Settings, Miscellaneous tab.

2. If you suspect that the recently installed "Rapid Security Response" is the cause: It can easily be removed:

Thank you! I do have "ignoresegv true" and "ignoreillegal true" set in prefs.

I'll try rolling back the latest security update and report back.

[nandrews]

Rolled back the RSR and I'm still getting segfaults. Executing from the command line reports "Unsupported ROM type" regardless of which known good ROM file I point to in prefs:

Code: Select all

Reading ROM file...

ERROR: Unsupported ROM type.

[nandrews]

It looks to me like this might be an issue with SDL... SDL compiles and I can build SheepShaver from source using the Xcode8 branch (instructions to use that build file are kinda buried, maybe that should be documented in the official build instructions?), but I still get the same segfault. Both are using the same known good ROM file (the one distributed as newworld86.rom).

Here's the segfault I get running the Dec 22 version under Ventura without the RSR patch:

[Ronald P. Regensburg]

The crash report does not give information about the crash that I can understand. Maybe others can interpret the crash report?

You executed SheepShaver from Terminal. Why did you do that?

At which point does SheepShaver crash? Immediately, or during startup? If during startup, at which point?

Earlier you mentioned that "Unsupported ROM type" is reported.
You did not mention the Mac OS version you run in SheepShaver. If earlier than MacOS 8.5, the new world rom file will be incompatible. It may work with MacOS 8.5, but If you run MacOS 8.5 or earlier, better use the old world rom file. (I am referring to the rom files that are available on the Redundant Robot site.)

Thanks, Ronald. I've executed both from the terminal (in order to see any error output directly from the binary) and from the GUI. Both crash immediately, before any Mac display appears.

This happens using both of the known good ROM files taken directly from Redundant Robot, and it occurs whether I specify the ROM file in prefs or simply rely on correctly naming them in the SheepShaver app directory.

I've only run up against this issue on my 2015 Retina MBP, running Ventura using OpenCore Legacy Patcher.

Since this only happens on your OpenCore machine, perhaps you should ask about it on the OpenCore forum? Probably no one else has ever tried to run SheepShaver on an OpenCore system.

You wrote:

I'm running Ventura via OCLP on two other Macs on which the Dec 22 2.5 build runs without an issue, the only difference being that the offending machine is the only one updated with the most recent Ventura security patches.

You also wrote that you again removed the update. Maybe the installation of this new "Rapid Security Response" caused a change in your setup that was not reversed by again removing the Rapid Security Response?

For the record:
This update did not cause any problems with SheepShaver on my regular M1 iMac. It still runs fine both natively and with Rosetta.

For who is interested:
Rapid Security Responses are a new type of security updates. The ones distributed last week (for macOS 13, iOS 16, and iPadOS 16) are the first updates of this kind. They can be removed again easily if they cause adverse effects. See: https://tidbits.com/2023/05/02/what-are ... important/

It's possible, I suppose. And I will ask there. But I'm running Ventura via OpenCore on several other machines as well, and this behavior does not occur... Very odd!

The OCLP documentation itself states that results will vary from machine to machine; depending on the hardware, OpenCore will have to patch different bits to get the OS to work. It's possible there's something specifically on the 2015 MBP that conflicts with the RR update in a way that affects SS. Possibly something to do with memory addressing.

Nobody in the OCLP community seems to have any insights here. Some suspicion that it might be a problem with some assumptions made about Metal addressing in libsdl2, rather than SheepShaver, but BasiliskII builds and runs just fine on the same machine, so it really seems like it's SheepShaver codebase specific.

Oh well. I have other machines.
