[Bug 47077] Brawlhalla (Steam) crashes with Wine 4.6 ( Steam Game Overlay Renderer hook engine can't cope with GOT/ PIC register load code at API entry, needs DECLSPEC_HOTPATCH for setupapi.SetupDiEnumDeviceInfo)

Hello Michele,

your backtrace indicates another hotpatch/PIC victim.

Call frame #1 -> gameoverlayrenderer = hook
Call frame #0 (crash site) -> AUDDRV_GetEndpointIDs (audio backend
GetEndpointIDs)

The instruction at crash site does GOT data access. It's very likely that the
hook engine copied the GOT/PIC register load code into the trampoline which
can't work by design.

Building 32-bit Wine with '-fno-PIC' on x86 is the "one solution to rule them
all". It will fix all hotpatch related issues, in fact making DECLSPEC_HOTPATCH
unnecessary (except for few broken apps that expect hotpatch signature at API
entry).

This is covered by bug 47097 ("Multiple Steam games crash on startup ( Steam
Game Overlay Renderer hook engine can't cope with GOT/ PIC register load
code)(Counter-Strike, Black Mesa, The Superlatives: Shattered Worlds, Lara
Croft GoL)") and friends.

Either build Wine from current Git/Source or wait for Wine 4.8 release.

Regards
