Strange, it sounds like GDB cannot access macros,which -g3 should
allow.

And it stays nil afterwards?  Or does it grow to include all the files
you expect to be natively-compiled as part of the session?  Is
maybe_defer_native_compilation called more than just once?  If so,
what is the value of Vcomp__delayed_sources for those other calls?
