--- Comment #81 from testator@protonmail.ch --- Here's the battlenetinstall with err+warn+fixme on staging-9.6 with WIP patch 20240407-2 https://pastebin.com/q2PPMbJW . It segfaults without showing the battlenet screen. I tried that hack in #56 you mentioned, it segfaults in the exact same way as in the pastebin for err+warn+fixme. In the previous trace from the generic CEF app it segfaults then unwinds at ntdll.longjmp according to the snippet posted. Perhaps that is enough info to track what's causing the segfault down now? It has to do with WoW64 i'd imagine since Kimball said it was working on their setup which probably isn't WoW64 because if it is then its a musl libc thing involving stack sizes probably.
