 Summary: mono build process segfaults on powerpc
 
 Hi,
 mono 1.1.11 (and 1.1.10.1 but not 1.1.10) segfault while building on ppc64
 machines running in 32bit mode. It works on an normal ppc.
 It happens every time but always in another file while compiling some c#

 Please run mono on gdb and give us a managed stack trace (using the
 mono_pmip () trick on every address).
 
 Am not able to reproduce this on MacOS X, maybe its a Linux issue.

+(Sebastian doesn't have access to the build daemons on which this is
+reproducible. I have access to a similar machine on the same network.)
+
+As Sebastian says, the failure isn't deterministic. Since the system
+on which I can reproduce this has two CPUs, and I think the build
+daemons have too, I'd be inclined to suspect a thread-safety bug?
+
+Here's a managed stack backtrace, as you requested. The command used
+was 'MONO_PATH="../../class/lib/default:$MONO_PATH"
