This also seems to happen on any site using the datejs library. The exact WebKit version is the one released with Qt 5.0.0. 810598 1 svillar 2013-01-18 07:46:26 -0800 I cannot reproduce it with current trunk.

I can reproduce this only on Linux, so may be Linux specific. 834710 4 arnaud.lb 2013-02-16 06:54:01 -0800 Reproduced on a Debian box (64bit kernel, 32bit userland) and an Ubuntu VM (32bit). Both "fancybrowser" and "browser" demos crash when loading http://datejs.com/ 862643 5 allan.jensen 2013-03-25 04:38:02 -0700 I can not reproduce this on 64bit linux. Could it be 32bit userland specific? 862724 6 arnaud.lb 2013-03-25 07:07:00 -0700 Yes, it seems. I've tried on a 64 bits ubuntu, and it doesn't crash there. Tried again on multile 32 bit systems, and it crashes on both. So it seems to be specific to linux with 32 bits userland. 863758 7 allan.jensen 2013-03-26 10:05:43 -0700 Confirmed on 32bit linux. #0 0xb051708b in ??
