1 on syntax error; just let yyparse do its thing.
* tests/glr-regression.at (Badly Collapsed GLR States): Likewise.
* tests/torture.at (AT_DATA_STACK_TORTURE): Likewise.
(Exploding the Stack Size with Alloca):
(Exploding the Stack Size with Malloc):
Expect exit status 2, not 1, since the parser is supposed to blow
its stack.  Problem reported by twlevo@xs4all.nl.

Expect exit status 2, not 1, since the parser is supposed to blow
its stack. Problem reported by twlevo@xs4all.nl.
* data/glr.c (yyparse): Don't assume that the initial calls
to YYMALLOC succeed; in that case, yyparse incorrectly returned 0.
Print a stack-overflow message and fail instead.
