Description Csaba Osztrogonác 2013-03-07 03:21:32 PST
Unfortunately we don't know the exact revision when they started to crash, 
because there is another serious bug which makes all inspector tests crash:

See https://bugs.webkit.org/show_bug.cgi?id=108632 for previous testing
(Comment #0 and Comment #1)

I'm going to bisect this regression manually with applying the fix
in https://bugs.webkit.org/show_bug.cgi?id=111441

Results on ToT with the fix from bug111441:
Comment 1 Csaba Osztrogonác 2013-03-07 05:18:23 PST
The bug was valid on r140000 - http://build.webkit.sed.hu/builders/ARMv7%20Linux%20Qt5%20Release%20%28Test%29/builds/7992 (only inspector tests was ran here)
Comment 2 Csaba Osztrogonác 2013-03-07 05:23:02 PST
all inspector tests crashed on r139004 - http://build.webkit.sed.hu/builders/ARMv7%20Linux%20Qt5%20Release%20%28Test%29/builds/7993
Comment 4 Csaba Osztrogonác 2013-03-07 09:20:16 PST
I got it r138609 is the culprit. It caused this regression
or revealed a hidden bug.

r138608 - http://build.webkit.sed.hu/builders/ARMv7%20Linux%20Qt5%20Release%20%28Test%29/builds/8001
r138609 - http://build.webkit.sed.hu/builders/ARMv7%20Linux%20Qt5%20Release%20%28Test%29/builds/8002

(Of course I applied the fix from https://bugs.webkit.org/show_bug.cgi?id=111441 to unhide this bug)
Comment 5 Csaba Osztrogonác 2013-03-07 09:21:06 PST
It might be similar bug on ARM Thumb2 to this ARM Traditional bug - https://bugs.webkit.org/show_bug.cgi?id=105930
Comment 6 Csaba Osztrogonác 2013-03-18 10:30:08 PDT
The proposed fix in https://bugs.webkit.org/show_bug.cgi?id=103146 fixes these crashes.
