Interesting – none of these tests seem to fail on my LLVM 3.2/x86_64 box.

In any case, the failure were not really caused by these commits, they only switched the Phobos version used for release builds to be compiled with -O3 -release.

Okay, these failures seem to be caused by a issue in GC.mark() which
only occurs on x86, and seems to be fixed in LLVM 3.2. Not sure what
the best way going forward here is?

Just using -O2 instead of -O3 on pre-3.2 seemed to do the trick. But
while my local tests and the new multilib builds on ci.lycus.org pass,
the Travis builds are still failing.

Need to reactivate my actual 32 bit VMs for testing, I suppose.

I'm still on the go, but fired up an x86 EC2 instance running Ubuntu
12.04 LTS, and the problem also occurs there.

Backtraces look like stack corruption:
Program received signal SIGSEGV, Segmentation fault.
0xbffff0e0 in ?? ()
(gdb) bt
#0 0xbffff0e0 in ?? ()
#1 0x00441f0f in ?? ()
#2 0x0cec8300 in ?? ()
#3 0x07d588a1 in ?? ()
#4 0x24048908 in ?? ()
#5 0xfed3b0e8 in ?? ()
#6 0x8601b1ff in ?? ()
#7 0xc4832648 in ?? ()

No idea what is actually going on here (related to exception
unwinding?) Need to further investigate this later today. I still
wonder what we should do about this concerning the release… Package a
LLVM 3.2-based version?
