Bug 122129 – ASSERTION FAILED when running inspector/debugger/pause-in-internal-script.html

• Status: RESOLVED
• Resolution: INVALID
• Component: Web Inspector

[Mark Lam]

With a debug build, run DumpRenderTree in a debugger.  And then have it run the layout test inspector/debugger/pause-in-internal-script.html.

=== BEGIN gdb dump ===
$ DYLD_FRAMEWORK_PATH=./WebKitBuild/Debug/ gdb ./WebKitBuild/Debug/DumpRenderTree
…
(gdb) r LayoutTests/inspector/debugger/pause-in-internal-script.html
