I'm curious: what makes you certain that this bug actually is a duplicate of
PR35204?  If you're not sure, and I'm not, then let's reopen the bug.
Someone who is sure can still mark it as dupe.

Thanks,
Ralf

Hi Ralf,

the segmentation fault didn't arise while generating "conftest" without
optimization. After some debugging of xgcc I found out that the segfault was
taking place during redundancy elimination (file tree-ssa-sccvn.c). 

This issue was specific to the host I was building on (Windows based) and due
to stack size limitations.

I hope this explanation is sufficient. Thanks for asking.
Marion.
