Bug 157126 – [GTK][Stable] JavaScriptCore crash in 2.12.2

• Status: RESOLVED
• Resolution: DUPLICATE
• Component: WebKitGTK

[Alberto Garcia]

JSC is reported to crash when opening this URL: http://gexpertise.fr/activites/metiers/stockage

This has been reproduced with the MiniBrowser in 2.12.1, but Carlos reports that 2.12.2 crashes as well. trunk seems to be working fine.

A workaround is to set JavaScriptCoreUseJIT=0

Here's the backtrace:

Program received signal SIGSEGV, Segmentation fault.

I'm not able to reproduce this with 2.12
