#pragma once on Linux Clang fails on random files, but deterministic

[datgame]

On the rare random occasion, this include guard problem happens when using #pragma once:

game//home/datgame/dev/project/game/sound.h:42:8: error: redefinition of "Sound_memory"
struct Sound_memory {
       ^
game/./sound.h:42:8: note: previous definition is here
struct Sound_memory {

Adding ordinary #ifndef/#define#endif include guards fixes it.

Does this happen with both GCC and Clang?

[datgame]

It only happens with Clang. GCC and MSVC don't have this problem. (my game compiles with all 3)

For me too. I also think that it started to happen in a recent clang version.
