Trampoline allocation failing about commonlibsse HOT 7 CLOSED

My trampoline doesn't overflow when calculating the range

from commonlibsse.

Interesting. I am getting an allocation failure with EngineFixes64 under wine, and was hoping it was a similar issue with calculating the lower bound

from commonlibsse.

It's much more likely it simply failed to preload and never allocated a trampoline in the first place

from commonlibsse.

skse64 plugin preloader - d3dx9_42 exe path: C:\steam\steamapps\common\skyrim special edition\SkyrimSE.exe loaded into SkyrimSE.exe or SkyrimVR.exe, proxying SkyrimSE d3dx9_42 funcs and registering preload hook success

[2021-01-31 20:09:05.232] [info] [main.cpp:137] beginning pre-load patches [2021-01-31 20:09:05.233] [critical] [SKSE/Trampoline.h:187] Failed to handle allocation request

I think that this means we are failing to allocate the trampoline, called from

https://github.com/aers/EngineFixesSkyrim64/blob/ccde2fdd1a33a356fb43dbb491b868fbddf00508/src/main.cpp#L97

but it's not clear to me how Initialize() gets called, since the error references a line in SKSE_PluginQuery

The reason I suspected the min limit was that wine seems to allocate from the bottom, but any info on how I can debug this further and figure out why it won't load on wine is much appreciated

That fact that it doesn't print the version should tell you it never preloaded
https://github.com/aers/EngineFixesSkyrim64/blob/ccde2fdd1a33a356fb43dbb491b868fbddf00508/src/main.cpp#L86
That trampoline was never allocated, and you can't allocate from nothing, so it fails.

I assume d3dx9_ dll is supposed to call Initialize() on the DLL? I am definitely seeing the preloader dll get loaded
00c4:trace:loaddll:build_module Loaded L"C:\\steam\\steamapps\\common\\skyrim special edition\\d3dx9_42.dll" at 0000000000420000: native

And I see here: https://github.com/aers/skse64_plugin_preloader/blob/master/d3dx9_42.cpp that it is supposed to trigger the Initialize function in the DLL. The last thing the DLL logs is success.

I'm not sure I understand the detour code, but I see it is doing something with "api-ms-win-crt-runtime-l1-1-0.dll", which is provided by wine runtime and not the windows DLL, which could be the issue?

That is the problem for wine, since that dll is already intercepted by wine, it never hooks. I compiled skse_plugin_preloader without the initterm dance, and it works fine. Thanks!
