The NetBSD libc malloc implementation performs its own out-of-memory check, presumably for performance reasons. The check makes a strong assumption about the address space layout, which is that memory- mapped pages are always located above the heap. However, this assumption does not necessarily hold on MINIX3, thus resulting in malloc reporting an out-of-memory condition without the system actually being out of memory at all. Evidence suggests that in particular dynamically linked (i.e., pkgsrc) binaries were affected by this issue - most notably git. Change-Id: If542fbace0a1cce12aa9e075d51992cbbbf26e94
