I traced the compare_file_data() function and the target file couldn't 
be opened (sharing error) and that's why the tests on line 554 failed. 
Don't know why SetupDecompressOrCopyFileA returns ERROR_READ_FAULT 
though in that next call.

You mean just in the setupapi tests before that error? It doesn't 
explain however why it only fails in some circumstances.

That's the easy way out ;). I do want to try to get to the bottom of 
this. We have many tests out there that fail intermittently, probably 
because of us not cleaning up properly or when running the tests a 
second time on a non-clean system.
