OK, for the record: I use OpenSuse 10.2 with glibc 2.5. According to http://www.cs.utah.edu/dept/old/texinfo/as/gprof.html#SEC1 mcount occurs in the gprof output but I haven't seen this yet (gprof 2.17.50.0.5).

(Should I inform the Open MPI people about atomic assembler locking code in gcc so that they can reuse it?) -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=32789
