I found a solution - at least on my Ubuntu 24.04 system.

Add "-Fl/usr/lib/gcc/x86_64-linux-gnu/13" to the compiler options (your 
application or global). The ~/.fpc.cfg had -Fl/usr/lib but that was 
obviously not extensive enough to find the GCC libraries FPC needed.

And gprof is back in action! :)
