Debugging threaded code on Linux

Debugging threaded code on Linux

[Evan Lavelle]

I'm having various problems debugging threaded code on Linux 2.4.7-10/RH 
7.2, with insight 5.3. ddd seems to be more stable, but I think it's 
using an earlier version of gdb (5.0). The problems include fairly 
frequent crashes, 'thread apply' not working well, and so on.

Does anyone have any experience of insight and LinuxThreads, and how 
stable it is? Should I be expecting this?

Thanks

Evan

Make certain that the problems are in Insight. As far as I know, it is
very unlikely for the GUI part (Insight) to crash. More often than not,
it is the backend (gdb). Try debugging your program using command-line
gdb 5.3. (I think you can use "insight -nw" or "gdb -nw".)

Threads should work. Can you post a backtrace of the crash?
