Re: *FvwmEvent: toggle_paging metal.au causes FvwmEvent to crash
2009/6/30 Manoj Srivastava sriva...@acm.org: Hi, This was reported by a Debian use. Please retain the CC to 438132-forwar...@bugs.debian.org so that the Dewbian BTS has a copy of your contribution. I have not been able to reproduce this crash, but I am passing it along in case someone here has a better view into this. Originally reported for version 2.5.21; and most recently reconfirmed for version: 2.5.23 and 2.5.25. --8---cut here---start-8--- EvwmEvent segfaults every time. I get this in my dmesg: FvwmEvent[3014]: segfault at rip 2af1873cfcdc rsp 7fff240ad048 error 4 I found out that if the following line exists in my config-file, FvwmEvent seg-faults at startup: *FvwmEvent: toggle_paging metal.au Also, after trying several modifications to the config-file, both FvwmEvent and fvwm seg-faults very easily. The config-file parser seems to be broken, at least on amd64. I've committed a fix for this to CVS. The introduction of a new module message in 2.5.19 made the event table off by one for the trailing events (breaking startup, shutdown and unknown), and if a config name didn't match a known event would cause deference of a uninitialized static array element. (gcc sets them to null) The patch is one line, but is just as unrouboust as before, and will break again with the introduction of new Module messages. A proper patch would change the handling of the module messages to skip messages not dealt with in the module. /Viktor

I get this in my dmesg: FvwmEvent[3014]: segfault at rip 2af1873cfcdc rsp 7fff240ad048 error 4 OK, so that's memory-related then. :P I found out that if the following line exists in my config-file, FvwmEvent seg-faults at startup: *FvwmEvent: toggle_paging metal.au Was this linked using librplay, out if interest? Also, after trying several modifications to the config-file, both FvwmEvent and fvwm seg-faults very easily. The config-file parser seems to be broken, at least on amd64. That's a rather bold statement to make about the config-file parser (I wasn't aware we had one per se. :P).I wasn't able to reproduce this either when I looked into it a while back. Unless the reporter can obtain a corefile, and hence a backtrace, there's not a lot to be done. -- Thomas Adam
