hello everyone, i've got a question: i have a process i am tapping, and everything is working well. the process has several threads and subprocesses it spawns. some of them use SIGARLM (SIG 14) to terminate themselves. When this happens, systemtap terminates itself. How can i control this behaviour?

systemtap: mcermak systemtap.git:refs/heads/mcermak/variance * release-3.0-194-g7a89766 / runtime/stat-common.c runtime/stat.c: Add references to relevant information sources. http://tinyurl.com/zuknrm7

okay, so the problem is: systemtap 3.0 terminates because the child used alarm() and got an SIGALRM, while systemtap 2.9 does not. Is there any reason the newer version behaves that way?
<mjw>
Guest31933, I don't know why, but that sounds like a bug. Could you file one (possibly with an example) at http://sourceware.org/bugzilla ?
<Guest31933>
i don't really have time at my hands to write a full bug report about it, since this is part of my thesis at uni
<Guest31933>
i mean, how detailed does it have to be?
<mjw>
Guest31933, well, you can just file it as you described above. If you are lucky someone can replicate it with that information and see if we can find the bug.
