Comment:

 This has to do with the fact that we don't recognize import libraries that
 are named anything other than ".dll.a" or ".lib". Unfortunately, msys2
 names all import libraries that they generate using `gendef` with a `.a`
 extension.

 It's currently trying to treat the library as a normal archive, resulting
 in the segfault because there's no executable code.
