Fix assert() segfaults with profiler (bug #39587, bug #39586). * profiler.cc (profile_data_accumulator::tree_node::exit, profile_data_accumulator::exit_function, ): Comment out assert() statements which are not valid when profile is called from within a function. * profiler.cc (F__profiler_reset__, F__profiler_data__, F__profiler_enable__): Use correct function name in Texinfo docstring. * profiler.cc (F__profiler_data__): define retval(1) first to resize return vector just once.
