--- Comment #34 from Justas L bucaneer@gmail.com --- GCC 5.3 with 64bit stack alignment has been out for a while. However, there was also a bug that prevented using forced alignment together with optimizations (-O1 or higher) and -fstack-check:
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=69140
It has been fixed, but I think it will be months before there's another stable release. Meanwhile, there's a workaround: using -fno-omit-frame-pointer (or alternatively, not using either optimizations or -fstack-check).
Question: is it alright to submit the Wine patch when it is known it might require compile-time workarounds?
