--- Comment #6 from Alexander Schlarb alexander-fd@xmine128.tk --- Hi! Just wanted to report that I'm also affected by this issue.
I own an Undertale DRM-free edition from Humble Store and it crashes on startup. Running `apitrace` also only produces the word "on".
However I found that at least once before it crashed the following message was printed to the terminal window:
LLVM ERROR: Unknown specifier in datalayout string
This error message seems to originate from line 395 of this file in LLVM: http://llvm.org/doxygen/DataLayout_8cpp_source.html
I have therefore attached a backtrace of `gdb` with `break llvm::DataLayout::parseSpecifier` just before the crash (there is also a pointer to a "shader" mentioned several times in the trace, but it doesn't appear to be a string and I'm not sure how to extract it unfortunately; if I can do better please just ask).
Running the game using `LIBGL_ALWAYS_SOFTWARE=1` works without issues and if I take an `apitrace` of this and replay it there are no crashes, but lots of LLVM diagnostic warnings. I have attached those as well.
Also if a developer is willing to have a look at this I'm willing to sponsor a (DRM-free) copy of the game.
