[cfe-dev] libclang crashes when using TU with PCH

[jaytee]

I'm generating a TU using a PCH file and libclang asserts and causes access
violation when I get cursor instantiation locations from that TU, if files
from which the PCH file was generated no longer exist or have been modified.

If I pass the unsaved buffer of file "header.h", which has been used with
the saved state to compile the PCH file, I also get wrong cursor location
information if I use these to generate a TU.

Does somebody know why is the PCH file so tied to the files on disk? Is
there a workaround for this issue?

Thank you!
