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.
