Description of problem: When tracing a 32-bit process, both strace and the process hang. kill -9 makes them quit. Version-Release number of selected component (if applicable): kernel-2.6.20-1.3071.fc7 strace-4.5.15-1.fc7 glibc-2.5.90-20 mozilla-1.7-0.3.2 (it's a really ancient super-old Mozilla for the experiment) How reproducible: Not easily, needs a long-running ancient 32-bit process, apparently. So far I only know about Mozilla doing it. Steps to Reproduce: 1. Install an old Mozilla (from fc5 or fc6). 2. Run mozilla & and find the PID (this way the trace is much shorter, no need for startup run) 3. Run: strace -o x.trace -f -p PID Actual results: Both hang Expected results: Strace working, process working Additional info: I'll attach the /var/log/messages with SysRq-T. It seems like all involved processes were captured, so this should be useful. The urgency is not very high, because I can kill the actors with -9. But who knows, maybe they leak something.

Reproduced on any more recent kernel?
