I have emerged glibc with "debug -glibc-omitfp" and restarted the system. But when I execute "valgrind /usr/lib/mozilla-firefox/firefox" I only see things like this: Invalid read of size 4 at 0x4018620: (within /lib/ld-2.9.so)
No filename:linenumber here. What does it take to get debug symbols from /lib/ld-2.9.so?
