Hi all,

Just wondering if anyone else has experienced the following problem with Firefox. 
If I open multiple tabs almost simultaneously, and try resolving multiple sites,
I often get a segfault.  Any combination of sites that require a bit of time
to load seems to cause the problem.

I'm running NetBSD 3.0/i386 stock from the installer CD, with firefox-1.5nb3
built from pkgsrc.  I'm not getting any segfaults with any other applications on
the machine, and I've tested the RAM (the machine has ECC RAM, which makes that
possibility less likely anyway).

I ktraced the application and also looked at the core with gdb, but I haven't tried
actually running a build with debugging symbols enabled.  This output probably
isn't too useful, I'm more curious if I'm the only one who's encountered this.

Here's some output from ktrace:

Here's the backtrace output from gdb:
