[Bug 27680] Multiple 64-bit applications crash on startup (violation of the Windows 64-bit ABI, stack pointer (RSP) must be 16-byte aligned when making a call to Win64 API)

--- Comment #30 from Justas L  ---
The gcc patch does (mostly) work - see my comment at
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=66697#c8

-mincoming-stack-boundary=3 allows Planetside 2 to launch and run, definitively
resolving bug 38775. However, curiously, -mstackrealign or compiling without
extra options and trusting force_align_arg_pointer still lead to the same
crash.

I also tested the program from bug 37719 (because it seems to be the
smallest/simplest among the listed duplicates), and it still crashes even with
-mincoming-stack-boundary=3. Perhaps there's a different or additional bug in
that case?
