Javascript dialogs, HTML 5 causes aborts/segfaults with sem loaded in www/firefox35

Mon Aug 17 00:20:16 UTC 2009

This is actually two separate bugs, although I have no doubt they are related.
Btw, before people start asking, I HAVE loaded sem.ko, as confirmed by kldstat.
These also occur in safe mode with all plugins disabled except for
"Default Plugin".
This is the latest firefox35 port. These bugs also survived a reboot
and only starting firefox and an xterm in twm. Note: I usually use
icewm with GTK applications.

Bug 1. The HTML5 video on the intro page.
It works, barely. Skipping backwards/forwards unreliably fails,
resulting in a segfault. It also uses 100% of CPU (enough to stop the
clock) for between 3-20 seconds while loading. Most of the time, it
doesn't fully load - or at least only plays a clip of varying length
from the beginning. Attempting to refresh the page with the video
expanded resuts in a segfault.
Bug 2. If javascript on a page attempts to open a dialog window of any
sort(prompt,alert,anything else except for a new tab) FF dies with the
message
Assertion 'pthread_mutexattr_settype(&attr, PTHREAD_MUTEX_RECURSIVE)
== 0' failed at pulsecore/mutex-posix.c:52, function pa_mutex_new().
Aborting.
Abort trap

This is exhibited on http://www.pageresource.com/jscript/jalert.htm
.Mousing over the the popup link causes an abort.
Oddly enough, that ALSO occurs while I'm shutting the browser window
with File->Quit.
I'm 90% sure that these problems have something to do with something
else I'm running.
Since I installed about 500 ports (literally) over the past 3 days, it
could be almost anything.
I recompiled with the DEBUG knob enabled. There are a LOT of failed
assertions and warnings while starting/running. I can provide the
entire logs on request, but here are several segments:

pldhash: for the table at address 0x2d79c4d8, the given entrySize of
