974	heap size > 4GB impossible on 64-bit	Jim Ursetto	Jim Ursetto	"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.

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)."	defect	closed	major	someday	core libraries	4.8.x	fixed
