Profiler flag (-pg) causing crash while configuring #72

Adding -pg to the compiler line (configure) makes gcc (within configure, i think) fall over (at least something is crashing).

I know that the crashlog doesn't really show anything obvious related to gcc, but since the only thing i changed was the profiler flag (-pg), i guess it might be gcc to blame. If not, please let me know and i post the bug report elsewhere.

Thank you

PS: Does the profiler need to be explicitely compiled into gcc? Like it was with -flto? Is profiling even supported (yet)? Crashlog_scummvm-conf_2019-05-22_08-25-32.txt

@Sebastian Is -pg completely unimplemented in our side, or there just bug need to be fixed ? I also tried to use it, but crashes as well

I've never looked into this so the effort to enable it is unclear, for me at least. Sorry.

@sba1

Find out that it crashes when I use -pg and with newlib compile, and with clib2. Just with clib2, you do have AmigaOS native implementation of profile(), so at least that one can be built with -gstabs, to see where exactly it crashes.

Probably some changes in elf.library or in kernel start to cause issues for some time and that profile() code placed inside of clib2's clib2/library/profile_profil.c need to be fixed
