load.c: avoid segfault when 'throw' occurs in the middle of rb_load_file_str
How can a 'throw' happen while the current thread is reading a Ruby source file from disk and parsing it? It can happen if another thread calls Thread#raise, and passes an Exception object which responds to #exception, and the custom #exception method calls Kernel#throw. In practice, this is most likely to happen if you combine the use of autoload and Timeout.timeout. An extra check is required to avoid a segfault in this case. * load.c (rb_load_internal0): extra check before returning TAG_RAISE when a non-local transfer of control happens while loading and parsing a Ruby source file.
