#1375 closed defect (fixed)

Invalid type syntax for pair segfaults the compiler

Reported by: megane Owned by:
Priority: critical Milestone: 4.13.0
Component: scrutinizer Version: 4.12.0
Keywords: Cc:
Estimated difficulty: easy


Compiling this kills the compiler (note the spurious dot):
(: foo (pair * . *))

Error: during expansion of (: ...) - segmentation violation

	Call history:

	<syntax>	  (##core#begin (: foo (pair * . *)))
	<syntax>	  (: foo (pair * . *))	<--

Thanks for finding this! It's a pretty serious problem, given that length will crash when passed an improper list.
