report bp-07df0710-619b-47d7-856b-860a32111004 .

This happened to me several times. When I leave firefox overnight and come back the next morning, I cannot resume my old sessions. Firefox 7.0.1 goes into the loop of consuming 50% CPU and its windows are never restored.

When I look at the sysinternal's process monitor, firefox.exe main process' Virtual Memory memory consumption jumps between 580Mb and 760Mb every second. It could show 580Mb one second then 760Mb the next second, then somewhere in the 600s Mb then again in the 500s Mb etc.

I left firefox run for 30 minutes before it crashed. Usually I kill it earlier. Process Monitor gave me several "Insufficient system resources" messages before FF crashed.

While FF was consuming the CPU, I saved several stack traces.

This looks sorta like that bug from before. Was that fixed in 7?
Oops, I just found it: bug 676934. The fix went into Firefox 9. Luke, do you think this looks like a dupe?
Yes, it does.
Actually, no.  On the stack it looks like content OOMs, that runs Firebug code which OOMs, and then it tries to report that exception, which OOMs and this all probably involves walking the stack a bunch of times.  I think FF7 is when the stackLimit when away and thus made it easier to get 50K-tall call stacks.  This OOM-while-handling-OOM problem should be addressed by bug 667915 which is currently in beta.
OOM does sound like what might be a problem for me. 

I compile various open source projects using MSYS tools. If I recompile ffmpeg and libfaac a couple of times, eventually sh.exe from MSYS tools starts crashing and dumping core. I've read that Symantec Antivirus and MSYS do not play together very well. Eventually I may not be able to access shared drives etc. I start getting "Not enough resources" messages. I have to reboot my PC at this point (logout and log back in does not help).

I think that is when I might see FF jump to 50% of CPU when I try to do some browsing.
Oops, I should have been more specific: I meant "runs out of stack space" which is different than exhausting heap memory.  function foo() { foo(); } is all it takes to exhaust stack space.

Do you get any hangs with this stack on mozilla-beta?
I will try to run a beta version for a couple of days. I will report back.
I hit the CPU thing today with FF 8.0 beta. It took browser 10-15 seconds before I got unresponsive script warning. I stopped the script and everything seems ok.

Btw, it is always accessing this website when FF/Firebug has trouble.
