ia64.

I experienced it, too.
An assertion

Iceweasel 17esr crashed immediately before it shows its window on ia64.


The failing assertion is *not* related with the crash. I didn't care about it.




The patch is similar to some bugfixes of earlier versions:

bug#659186 gnome-shell: Segmentation fault in libmozjs185.so.1.0 at startup

GLib-CRITICAL **: g_slice_set_config: assertion `sys_page_size == 0' failed Furthermore the testsuite sometimes crashed when I built the unpatched iceweasel 17.0.8esr-2 on ia64. The reason for the crash is a known one: The Mozilla JS engine needs pointers have their high 17 bits cleared because it would break a variant data type which the engine uses. The patch doesn't fix the failing assertion. It will still occur, but the crash is gone. The patch is also important for the libmozjs17d package which will be used by gnome-shell soon. bug#696041 ia64 (Itanium) Mozilla JS engine needs pointers have their high 17 bits cleared

I'm having the same symptoms (same assertion failure and crash at
startup) on amd64.

The amd64 arch isn't affected by the ia64 crash which this patch addresses, believe me ;-)

I suggest filing a separate bug report for the crash on amd64.


Cheers
