Bug 111704 – REGRESSION(r138609): 170 inspector tests crash on ARM Thumb2

• Component: New Bugs
• Status: RESOLVED DUPLICATE

[Csaba Osztrogonác]

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:
https://bugs.webkit.org/show_bug.cgi?id=111441

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:
http://build.webkit.sed.hu/builders/ARMv7%20Linux%20Qt5%20Release%20%28Test%29/builds/7987

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)

[Csaba Osztrogonác]

all inspector tests crashed on r139004 - http://build.webkit.sed.hu/builders/ARMv7%20Linux%20Qt5%20Release%20%28Test%29/builds/7993

[Csaba Osztrogonác]

all tests crashed on r138500 - http://build.webkit.sed.hu/builders/ARMv7%20Linux%20Qt5%20Release%20%28Test%29/builds/7994

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)

[Csaba Osztrogonác]

It might be similar bug on ARM Thumb2 to this ARM Traditional bug - https://bugs.webkit.org/show_bug.cgi?id=105930

[Csaba Osztrogonác]

The proposed fix in https://bugs.webkit.org/show_bug.cgi?id=103146 fixes these crashes.
