Wow! I think what's happening here is that the load is continuing while the alert box is up. I'm pretty sure this shouldn't happen at all -- the box should block page loading.

[Martin Robinson]

It would be useful to have the stack trace from DumpRenderTree as well.

Here is the stack trace from DRT. Patch in the bug #85134 is needed to reproduce the crash with DRT.

Core was generated by `WebKitBuild/Debug/Programs/DumpRenderTree LayoutTests/loader/load-defer-resume-'.

[Martin Robinson]

It seems that the fact that the assertion happened during the alert box is a red herring. While that behavior is clearly wrong, this assertion failure seems to be caused by something else.

[Martin Robinson]

Looks like Soup is calling WebCore::ResourceLoader::didReceiveResponse on a resource that is deferring it's loading.

[Dan Winship]

hm... the call to soup_session_pause_message() in sendRequestCallback() is wrong... It ought to be just "return;", but then there also needs to be logic in platformSetDefersLoading() to handle the case of undeferring at that point (since it will need to call didReceiveResponse() then).

The pause_message() issue is tracked in bug 84955

Not sure if this actually works, because I'm getting tons of test failures with or without this patch...

That turned out to be libsoup's fault, and that's fixed in git now. The patch works.

Minor nit: The line here should be the title of the bug.
