I'm seeing this crop up with other browsing too.  For example, leaving fennec idle for a few minutes, clicking a link from digg.

Running from terminal, I see this output:

pure virtual method called
terminate called without active exception
Aborted

try using /fennec instead of /firefox

attach windbg when you get the dialog,
!analyze -v -f
~* kp

attach the log.

How would I do this on an N810 running Maemo?

I can't seem to get fennec to run with gdb.  I see no different output running "fennec -g -d gdb" than I do "fennec".

I tried loading GMail on my n810 after landing the cache patch in bug 448073. GMail loaded for me and I was able to open and read some email.

My best guess is that this was fixed by the cache patch, so I'm closing it out.  If you see it again, please reopen.

This still crashes for me on Maemo on my 810 using the 7/19/2009 build.

could this be a memory issue?

I wonder if turning on virtual memory on the N810 would make the difference.  I have seen a similar problem going to a totally different site (http://www.pbs.org/newshour) with both 1.0b2 and 1.0b3.  In fact, I would get the exact same messages at the terminal ("pure virtual...") if I ran "fennec" from the command line.  Today after installing 1.0b3 I ran into the same problem.  Before submitting bug about the problem, I happened to notice the suggestion from Bug 511451 regarding turning on virtual memory on the N810.  After doing that, I didn't get the crash any more with http://www.pbs.org/newshour .  I was actually able to look at the page and listen to various news stories.  It's worth a try.

I suspect many crasher bugs with Fennec relate to memory and can be resolved by turning on virtual memory.  However, for whatever reason, I can't seem to enable it on my N810.  This is conceivably a serious issue for other users who cannot enable virtual memory.

I had a similar issue with my N810.  At first, I enabled virtual memory with a size of only 24 MB just to be conservative.  Enabling virtual memory worked as did Fennec once virtual memory was enabled.  I tried changing the size of the virtual memory to 128 MB and got errors saying that it couldn't enable virtual memory, giving me a message like "Unable to create virtual memory".  At that point, no matter what size I chose for virtual memory, I couldn't get virtual memory working again.  Eventually I came across the following solution:  http://talk.maemo.org/showthread.php?t=18043 .  It comes down to a latent problem in the formatting of the internal 2GB memory card on the N810.  If you back up the data from the internal card (/media/mmc2), reformat the card, and then restore the previous data, there is a good likelihood that you can get virtual memory working (assuming you have the space) through the Control Panel.  It worked pretty smoothly for me.  BTW, I tried the "File Manager" approach for reformatting since it was substantially easier and it worked just fine.  The only odd thing that I remember from the whole process was that I have a few files that could not be backed up properly using "tar", possibly due to the formatting problem.  I ended up deleting them so that my "tar" archive would complete error free.  Anyway, it might be worth a try to get virtual memory working.
