Seems reasonable, if we can.

IIRC, the issue is that the mechanism for concatenating the tokens
back together frees the input strings
static char *
cat2_str(char *str1, char *str2)
{
char * res_str = (char *)mm_alloc(strlen(str1) + strlen(str2) + 2);
strcpy(res_str, str1);
if (strlen(str1) != 0 && strlen(str2) != 0)
strcat(res_str, " ");
strcat(res_str, str2);
free(str1); <------------------
free(str2); <------------------
return res_str;
}
So that ought to dump core if you don't make all the productions
return malloc'd strings. How did you work around that?
(Maybe it'd be okay to just leak all the strings?)
