--- Comment #3 from Daniel Starke <daniel.f.starke at freenet dot de> 2013-01-28 11:53:14 UTC ---
I can confirm this bug for gcc 4.7.2 mingw64. The -mstackrealign command-line
flag can be used as workaround as described on
http://stackoverflow.com/questions/6716654/segmentation-fault-using-openmp-and-sse
until this bug is properly patched.
