| 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. |

Endless recursion in optimizing (x - 8 != 0) where x is an add pointing to inself: This happens if dead loops are constructed with only ONE predecessor, then Phi-nodes are removed, leading to cycles in data path ... |
