In impure push mode, don't allow more than one yypstate to be allocated
since multiple impure parsers would corrupt yynerrs. * data/push.c (yypstate_allocated): New static global variable initialized to 0. (yypull_parse): If yypstate_new returns 0, don't report it as memory exhaustion if yypstate_allocated is 1, but still return 2. (yypstate_new): Invoke yyerror and return 0 if yypstate_allocated is already 1. Otherwise, set it to 1. (yypstate_delete): Set it to 0. * tests/push.at (Push Parsing: Multiple impure instances): New test case.
