I just hit this fatal assertion:
Assertion failure: !cx->isExceptionPending(), at /home/dbaron/builds/ssd/mozilla-central/mozilla/js/src/jscntxtinlines.h:242
while switching tabs on flightaware, I think on
http://flightaware.com/live/flight/CAL4/history/20140401/1630Z/RCTP/KSFO
I think the assertion is happening around a console.log call. I'll attach debugging info and the script.

Oh, and I was running an Linux 64 self-built debug build, started at Sat Mar 29 11:02:47 PDT 2014, running what to me is locally revision 4a7e12b30a9d, which is https://hg.mozilla.org/mozilla-central/rev/c69c55582faa plus local patches.

Is this because console.log is using the JS API wrong in some way?

It's possible, though I thought we'd made sure we cleared pending exceptions as needed.
I just tried to reproduce by loading the URL from comment 0, doesn't seem to reproduce for me. :( Same thing for nytimes.
I'll take a more careful look on Wednesday, I guess (I'm off tomorrow and Tuesday).

Yeah, it's not reliable; I've seen it a total of two times, both documented here, on sites that I use regularly.
