[cfe-dev] Assertion `Index < LocalSLocEntryTable.size() && "Invalid index"' failed.

Could you post the whole source?

Where are you getting the SourceManager that you calling
`sm->getPresumedLoc(loc)`
on? It is important that you call that method on the same SourceManager
that is in the CompilerInstance that clang is using.

Also, you probably want to use `sm->isFromMainFile(loc)` instead of getting
the presumedloc, since the presumedloc can be modified by `#line`
directives and other stuff.
