The values of the pointers in the function call:

    client->didReceiveData(handle.get(), chunk->data, chunk->length, -1);

seem OK, so not sure of what's going on here.

I seem to be able to reproduce this 100% with this link: http://javierparra.eu/?p=721

I'm fairly sure that this is a dup of https://bugs.webkit.org/show_bug.cgi?id=72883 because running it with valgrind  I get the same assertion in JSC code.

Just to clarify, I get Xan's trace when running with gdb but when I use valgrind I get the same assertion than the one I copy pasted in https://bugs.webkit.org/show_bug.cgi?id=72883

[Sergio Villar Senin]

I'm closing this a duplicate as the traces are exactly the same.
