Description Aniruddha Shankar 2006-04-21 11:51:29 UTC

I use nvu off and on, and I've noticed occasional crashes. One of the machines I have runs as a debug machine - it's compiled from the ground up with debugging support and nostrip. I used nvu on this machine, editing the /usr/bin/nvu shell script to enable debug output and invoking nvu as "nvu -g", as reported in http://snipurl.com/piht .

Sure enough, nvu crashed again and I ran bt in the gdb window to capture the crash. 

Something was wrong, though because the stack trace I got does not give any helpful information. This is not because of some stripped or non-debug library, since ALL of "system" and almost all of "world" is compiled with -g -ggdb -ggdb3, FEATURES=+nostrip.

I've googled but the nvudev.org forums are horribly unorganised. I can't believe there's no public bug tracker or public information on debugging nvu. 

Here's the information I was able to glean:

I would appreciate any pointers on how to further resolve this.

Comment 1 Jory A. Pratt 2006-06-24 18:30:02 UTC

get a backtrace using /usr/lib/nvu/nvu-bin instead of invoking the bash script.

We need a backtrace, see above.
