Bug #3114: Using malloc(size_max) gives strange results
http://bugs.dragonflybsd.org/issues/3114

----------------------------------------
While porting d-lang dmd/druntime/phobos to DragonFlyBSD, it became apparent
that using 'malloc(size_t)' to deduce malloc and alignment rules, gave some
unexpected results.
Example:
malloc size:9223372036854775807, malloc failed, ptr == NULL, errno:12
// expected result (INTPTR_MAX)
malloc size:72036854775808, ptr == 0x800800000
// this is fine
malloc size:18446744073709551613, ptr == 0x800455000
// unexpected UINTPTR_MAX / SIZE_MAX
