I didn't manage to reproduce this crash on top of trunk (r168619) on my Ubuntu 12.04 (x86_64). Do you work on other revision or architecture, or not the default config?

I gave it a shot with the latest revision r168673 but it crashes. I am using the default config with supported architectures i686 i386. I could not find any relevant information on the support for web inspector in 32 bit architectures.

Did you get this crash on x86_64 and x86 (32 bit) too? Did you get this crash in release and debug mode too? Which Linux distribution and GCC version do you use? This bug might be related to a specific GCC version and/or a distro specific compiler option.

(Debug builds fail due to RAM constraints) I do not have a x86_64 (64 bit OS) configuration at present, hence I cannot verify if the crash happens on a 64 bit OS.
Thanks for the information, it seems it is a bug in 32 bit backend of JSC. It might be a DFG JIT bug. Unfortunately I don't have installed 32 bit Linux or OSX. :( I cc JSC developers, I hope they have any hints what is this crash. And maybe it is a valid bug on OSX too, I can't check it myself.

Just an update, I have disabled the JIT and am able to launch the Web Inspector. This further confirms that the problem indeed lies in the 32 bit backend of JSC. The issue still persists with JIT enabled.
Closing this bug because the EFL port has been removed from trunk. If you feel this bug applies to a different upstream WebKit port and was closed in error, please either update the title and reopen the bug, or leave a comment to request this.
