Also it looks like your output is missing debug symbols (see http://wiki.winehq.org/Backtraces).
Yeah, forgot to switch my build system from "release" into "debug" profile so CFLAGS ended up being "-g -O2" during build instead of usual "-g -ddwarf-2 -O0". Would rebuild Wine later this evening and retest.
