Summary

0000003: Attempting to compile crc32.c in zlib-1.2.3 loops infinitely

Description

To reproduce, download http://www.zlib.net/zlib-1.2.3.tar.gz [^]
set CC to cparser in the Makefile and `make`

When it tries to compile crc32 it appears to loop infinitely, consuming much memory. I terminate the process before it goes over 1GB resident.
