finstrument-functions issues

[Matthew J Fletcher]

Hi

Has anyone tried with -finstrument-functions with the rtems-5 branch a (gcc
7.5.0) ? even with a minimal stub (shown), i get random crashes, normally
in the heap allocate/free code paths

__attribute__((no_instrument_function)) void __cyg_profile_func_enter (void
*this_fn, void *call_site)
{
}
__attribute__((no_instrument_function)) void __cyg_profile_func_exit (void
*this_fn, void *call_site)
{
}

Removing  -finstrument-functions from the makefiles removes the crashes.


regards
