Description linas 2002-11-15 19:06:20 UTC

I've got a crazy crash/hang that occurs when I close a 
gtkhtml window.  I am not sure if its gtkhtml's fault,
gtk's fault, glib's fault, something in libc6 or possibly 
a weird guile-glib interaction  ... ???

I'm not sure how to debug this, short of the  brute-force approach of
installing libc6 from source, and trying to figure out what mallopt 
does ...:-(   Any suggestions?

Is this bug unique? Is it a dup of another one? Is this a 'known bug'?

Comment 1 Owen Taylor 2002-11-15 23:05:18 UTC

Basically you are causing memory corruption somewhere.

A) Try setting the MALLOC_CHECK_ env variable to 2,
   this turns on more strict checking in glibc.
B) Use a memory checking tool like valgrind.

Comment 2 Owen Taylor 2002-11-17 15:34:43 UTC

Nothing we can do here from the GTK+ side.

Comment 3 Elijah Newren 2003-07-04 23:25:41 UTC

For future reference if anyone runs across the bug, the stack trace
looks similar to the ones in bug 98308, bug 112548 (which had some
potentially interesting comments at the end), and bug 115666.  Each of
these bug reports was on a Debian testing/unstable system.
