I didn't know what cproto does (I confused it with cdecl, but that's
besides point), so I just entered a couple of random lines, and it crashed,
like this:
/home/nyh$ cproto
/* stdin */
a
hello
"stdin", line 2: syntax error at token 'hello'
zsh: segmentation fault  cproto

I know "a" and "hello" aren't very useful C instructions, but cproto should
not be crashing even in that case.

Reproducible: Always
Steps to Reproduce:
1. run cproto	 
2. type "a" and newline
3. type "hello" and newline
4. watch the fun.
	

Actual Results:  /home/nyh$ cproto
/* stdin */
a
hello
"stdin", line 2: syntax error at token 'hello'
zsh: segmentation fault  cproto


Expected Results:  Anything but a core dump...
