--- Comment #31 from Justas L bucaneer@gmail.com --- Correction: using the updated version of gcc patch ( https://gcc.gnu.org/bugzilla/show_bug.cgi?id=66697#c11 ) and compiling Wine with -mincoming-stack-boundary=3 fixes bug 38775 (Planetside 2), bug 37719 (BatToExe) and bug 39267 (Unity), while the testcase URL provided in this report fails with a different crash report (I guess that's to be expected for a very outdated MMO client). Didn't test others but I suppose this counts as a fix.
