FVWM Version: 2.6.5 FVWM_MODULEDIR: /usr/libexec/fvwm/2.6.5 FVWM_DATADIR: /usr/share/fvwm FVWM_USERDIR: /home/sd/.fvwm Description: fvwm occasionally crashes (a few times a day). Repeat-By: Since I've started trying to take note of when it crashes, every time it was when I was - switching tabs in firefox, - opening a new tab in firefox, or - closing a tab in firefox. (I'm currently running ffx 38.6.0esr but this crashing problem has been occurring on and off for quite a while, so it is not specific to that particular version of ffx). However, I'm not certain that changing tabs in firefox is the only time it happens.

(gdb) quit ---------------------------------------------------------------------- FWIW: (1) I'm using Slackware64-14.1 on a Fujitsu T900 with a Core i7 M620, 8 GB of ram. (2) I've let memtest86 churn away for a long time with no reported problems. No other program on my system is showing any problems, so while I'm not certain that it isn't a bad hardware problem, I don't see any evidence of that either. I saved a couple of core dumps. If further information from those would be of use let me know.
