Just out of curiosity, does C89, or whatever standard we follow, allow this?
int
somefunc(int x)
{
int foo[x];
/* use foo[] for scratch space */
}
Obviously this is a bad plan if x can be a big number because you
might crash your stack, but suppose we know that's not an issue? It
seems a shame to have to do palloc/pfree in a situation like this.
