Paranoia checks...
FATAL: sc->regs->gpr[2] in signal handler (00000040) doesn't have expected value (affebad5)
Maybe you need a different kernel?
The host machine is a 1.5 GHz G4 with 1 GB of RAM and running OS X 10.4.
I could not get SS to compile (a fink issue I think) under Tiger so I only tried Gwenole's binaries; none worked. I only have one machine so I couldn't try to reproduce the error in a differrent context.
SS seems to die before even parsing the prefs so I won't reproduce them here.
