Yes, without it an assertion fails before the bug would cause a segmentation fault:
ICE: Assertion 'context_p->scope_stack_size == PARSER_MAXIMUM_DEPTH_OF_SCOPE_STACK' failed at jerry-core/parser/js/js-parser-expr.c(parser_parse_class):1068
Error: JERRY_FATAL_FAILED_ASSERTION

Well, this sounds like another bug. Assertions should never fail. Maybe another '}' related bug for classes.

Oh I was mistaken, I was looking at a different branch.
With this patch applied this assertion does not fail with that line removed and the correct syntax error is raised.
