Summary: [PPC] Unhandled Exception:
System.ExecutionEngineException: SIGILL
Product: Mono: Runtime
Version: 1.2.6
Platform: PowerPC

Component: JIT

Starting with Mono 1.2.6 we get a SIGILL for at least 2 known applications (mcs
and gmcs)
The system runs Linux/PPC and the CPU is a Dual G4 PowerPC 500Mhz.
It seems to be reproducible and happens on every mcs/gmcs invocation.
The issue came visible on our buildds trying to build gtk-sharp2 and beagle and
both failing with:
gtk-sharp2:

Unfortunely there are not stack-traces at all.
To get the complete build logs, check this out:
http://buildd.debian.org/fetch.cgi?pkg=gtk-sharp2;ver=2.10.2-4;arch=powerpc;stamp=1198566240
http://buildd.debian.org/fetch.cgi?pkg=beagle;ver=0.3.1-2;arch=powerpc;stamp=1198568376
I could find a build log of gtk-sharp2 (running in the same machine as above,
malo) which used Mono 1.2.4, and didn't abort/crash:
