FWIW, this is working for me (GCC 12).  I'm investigating another bug with
-fdebug-prefix-map and LTO, and thought this one would be related.

It works fine for me with GCC 7, 9, 10 and 11 on x86_64-linux, not sure which
version Mark used to reproduce.

Can you confirm it now works?

Replicated. With -flto added the result is a linker error:

g++  -g -o app/app app/app.o -L./lib -lA
/usr/bin/ld: /tmp/app.BSgkYr.ltrans0.ltrans.o: in function `main':
//app.cpp:6: undefined reference to `Lib::func()'
collect2: error: ld returned 1 exit status

Removing -fdebug-prefix-map (but keeping -flto) things build fine.
