--- Comment #18 from jordan triplesquarednine@gmail.com 2013-04-18 20:10:14 CDT --- I got a response on GCC bug tracker;
IIRC this is usually due to mis writing of memcpy/memset where you return null rather than the dest (first argument).
See PR56881 -> http://gcc.gnu.org/bugzilla/show_bug.cgi?id=56881
the segfault appears to be a bug in wine afaict from looking at 56881 bug report.
anyway, if there is anything more that i can do, let me know.
