 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).
