After upgrading to 4.18 project halts on assertion. Is there any solution for this?

LogRHI: OpenGL MajorVersion = 4, MinorVersion = 5, ShaderPlatform = GLSL_430, FeatureLevel = SM5
UE4Editor: elf_end.c:53: int elf_end(Elf *): Assertion `e->e_activations == 0’ failed

Arch Linux, Radeon HD7970

I’m not sure that this commit responsible, just lookin for possible cause. Now i’m trying to force redownload of dependencies, since they cached by GitDependencies

Thanks! Recent commit from 4.18 branch solves this problem.

Yes, that commit is most likely responsible. Visibility of elf_end() was changed to resolve another problem linking with a library that itself used libelf, but this apparently is still causing incompatibilities with AMD drivers (which use libelf as well).

Thanks for confirming!
