I've been using WindowMaker in Gentoo for nearly 20 years now, and have grown quite fond of it. It does everything I need quickly and efficiently. However, recently I've been getting frequent segfaults, causing WM to restart or crash. This is a message I got:
Code:

Apr 23 12:45:12 xxxx kernel: wmaker[26347]: segfault at 21 ip 000055c8dc1e1f8b
 sp 00007fff0bf20620 error 4 in wmaker[55c8dc1b3000+63000]

Apr 23 12:45:12 xxxx /usr/bin/wmaker[26247]: (MonitorLoop(monitor.c:133)): warning: Window Maker exited due to a crash (signal 11) and will be restarted.

I tried rebuilding WM but it didn't help. I guess it's getting long in the tooth and perhaps is not being maintained much anymore. Anyone have any ideas, other than "use another desktop environment"?

You could try to debug it. Rebuild with symbols. Grab a core file when it crashes. Post the backtrace and register context.

OK, sure. However, I have no idea how to do this. If you can point me to instructions I will try.

I'm a very long standing fan of WM too, especially because I can't even remember the last time I had something like a crash. It is definitely still being actively maintained so I wouldn't suggest using a different WM... there was a new release quite recently, which version are you running? Have the crashes started after installing the latest version (if you have?)

See https://wiki.gentoo.org/wiki/Debugging for retaining symbols.

I'm running the latest testing version, 0.95.9. This was installed about 2 weeks ago. I think these crashes started a few months ago when I started using a TV as my monitor (long story; don't ask). That couldn't have anything to do with this, could it?

OK, it looks like it was the TV. I switched to a regular monitor and the segfaults have gone away. I still get occasional restarts, but it's nothing I can't live with.
