No, it's not a transient issue, as I've been able to reproduce a
similar (but not identical) crash. The thing is that it fails when
building on a ppc64le machine (the gcc112 autobuilder instance). I just
reproduced it:

Unhandled Exception:
System.ExecutionEngineException: System.IndexOutOfRangeException: Index was outside the bounds of the array. ---> System.IndexOutOfRangeException: Index was outside the bounds of the array.
   --- End of inner exception stack trace ---
[...]

So it seems like host-mono doesn't build on a ppc64le machine. Looking
at the host-monolite tarball, I see it's a bunch of .dll built for x86.
Is this supposed to work on other architectures as well?

Thanks,

Thomas
