SEH: Save EXCEPTION_RECORD and CONTEXT on heap when jumping back from the exception handler to execute the except() filter expression because they are stored on stack and may be overwritten during execution of the filter expression. This fixes garbage in structures pointed to by _exception_info()'s pointers.
