Description

arthurmaciel posted a program which crashed when compiled or hung in csi. Although the original problem was fixed by increasing maximum heap size over 2GB, another problem surfaced: heap resize over 4GB resized to 0, resulting in crash.

$ ./test -:d -:hm16G
...
[debug] resizing heap dynamically from 2097152k to 4194304k ...
[debug] resizing heap dynamically from 0k to 1024k ...

This is due to heap_size being unsigned int instead of size_t. Proposed patch posted to chicken-hackers. His program is attached (warning, it requires about 8GB and 15 minutes to run to completion, but problem is demonstrated after a few minutes).
