GDB Backtrace for the GTK port when running the test inspector-protocol/debugger/setBreakpoint-dfg.html on r176918

Since r[176459-176503] (I was not able to identify the specific commit, only that range) the layout test inspector-protocol/debugger/setBreakpoint-dfg.html crashes on platform GTK.

The same seems to happen for platforms EFL and AppleWin

Before that it was flaky. Check 128736.

I'm attaching a GDB backtrace for port GTK on r176918

Maybe (just guessing, didn't tested) the revision causing the regression was r176479 (is inside the range) and it caused another regressions on the inspector. Check bug 139359.

Marked accordingly on the GTK expectations on https://trac.webkit.org/r176922
Comment 3 Marcos Chavarría Teijeiro (irc: chavaone) 2015-04-17 03:28:42 PDT
The test is flaky since r179015 (http://trac.webkit.org/changeset/179015).

When it fails the diff is the following:
