Comment 19 for bug 1066046

Created attachment 139221
Attempted gdb diagnostics

OLPC is moving from xulrunner to webkit. This is working great on our x86 laptops, but not on our latest ("XO-1.75") ARMv7 laptop.

We are running Fedora 17 with webkitgtk-1.8.1 (GTK3).

On the ARM platform, loading a javascript-heavy webpage causes a crash. Reproduced in Epiphany and OLPC's own "Browse activity" for the Sugar desktop. Reproduces very easily - loading gmail or Google Docs will cause an instant crash most of the time.

Unfortunately gdb is not helpful with the crash. With all relevant debuginfo packages installed:

(gdb) bt
#0 0x00000024 in ?? ()
#1 0x49f0eaf4 in ?? ()
#2 0x49f0eaf4 in ?? ()

The crash can't be reproduced on identical configuration on x86.

WebKit was built with these options:
