Found the same issue in relation to LLVM: http://old.nabble.com/C%2B%2B-Exception-Handling-Problem-td22427938.html

Solution from above thread: "My guess here is that there are JITted functions in your stack. If that's the case, you need to set the ExceptionHandling flag of LLVM on. This will make the JIT generate dwarf tables for JITted code, and libgcc
will be able to unwind these functions."

So the ideal solution for us would be to have dwarf table generation in JSC (that would have to be explicitly enabled, e.g. through a QWebSettings flag).
