Just realized another problem -- I don't think I can use goto across
functions like this. And even if the goto was valid in parser_alloc(),
I'll need YYNOMEM for other functions, like strdup(). The simplest thing
to do is probably shim YYNOMEM in my parser and use it directly:

#ifndef YYNOMEM
#define YYNOMEM goto yyexhaustedlab
#endif
