Is this true?
Yes, it is...
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! :)
Can you please add an issue to the bugtracker:
We should probably scan /usr/lib during installation for this path and add
it to the default generated fpc.cfg
