After iconifying mozilla (www.slashdot.org was the last page visited and maybe
there was an animated GIF, cannot say this for sure, mozilla suddenly crashed.
It was up for perhaps 10 hours.  Hasn't happened before.

gdb showed the following backtrace:

This probably is not too informative.  That it crashes in free strongly suggest
a double-free.  The malloc in glibc does not handle this (on purpose).

I guess you'll simply acknowledge this.  The problem I see is that the debug
information in the DSOs seems to be missing.  I cannot understand how you can
put up for download and test versions without debug information.  I thought this
is the purpose of the whole exercise.

Anyway, this is on a Red Hat 7 system but this should not be a problem.  The
binary is the nightly build downloaded last night.

Reproducible: Didn't try
Steps to Reproduce:


Expected Results:  Not crash.

so far this is a works for me. plus the state of necko has changed significantly 
from when this was filed. I am closing this as such. Please reopen if you still 
see the problem.

reporter:

This bug is a "futured" or "untargeted" bug which has been "resolved/works for
me". Most bugs meeting this criteria are usually somewhat out of date or working
in the current builds.

If this bug is not happening for you in a recent build (such as the Mozilla
daily build, Mozilla 0.9.3, or Netscape 6.1), please use the friendly "Mark bugs
as VERIFIED" radio button to set this bug to "VERIFIED/WORKS FOR ME"
If you reported the bug on a platform (e.g. Linux) and other contributors
reported on another platform (e.g. Mac OS), please comment that it works for you
 but do not verify it yet.

For these multi-platform bug reports, we need to verify all reported platforms
-OR- create new "still broken on platform X" bugs when you verify.

Didn't happen in a long time so I assume it's fixed.
