You can then use /usr/proc/bin/pstack on the process (which will yield a stack trace for each lwp). You can also use /usr/proc/bin/pmap to get all the mappings for the process. Using this data, you can determine what file contains the code at the %pc address (sounds like it's expected to be libXm.so.X). Now if you're really keen, you can dis(1) the shared object and map the %pc to an actual instruction. In any case, you should have enough information make a kickass bug report. (You can use /usr/proc/bin/prun to resume a process thus stopped) -g
