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

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)

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

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