This appears to be fallout from the TM merge. http://tinderbox.mozilla.org/showlog.cgi?log=Firefox/1280634101.1280634996.24011.gz Assertion failure: !(addr & GC_CELL_MASK), at e:/builds/moz2_slave/mozilla-central-win32-debug/build/js/src/jsgc.cpp:412

Is this a GC/CC outside a request maybe?

GC makes its own request, there's never been a requirement to begin a request before calling JS_*GC and end it after (doesn't seem necessary in any case). Is CC separated now? If so, it shouldn't need a request either. /be
