Description Boris Zbarsky [:bz] (still a bit busy) 2005-09-06 22:09:51 PDT
This bug is intended to track work on getting us to start with WAY_TOO_MUCH_GC

First step is bug 305884, of course.

With the patches I just attached to bug 307560, bug 327708, bug 327712, and bug 327716, I can start Firefox under WAY_TOO_MUCH_GC.

debugging code used to debug these

I may want to get bits of this in; I'll discuss with brendan sometime.

With the debugging code attached (the js_LockGCThing debugging is from other debugging, of leaks), I:
 * defined WAY_TOO_MUCH_GC (in patch, actually)
 * ran firefox under gdb until assertion failure or crash
 * looked at the GCThing in question (not necessarily the first one I looked at, but always the first or second for those 4)
 * found its address in JSGCThing.alloc with 
    grep -A 50 ADDRESS JSGCThing.alloc | fix-linux-stack | less -S
 * used the Ctor and Dtor stacks to figure out what happened
