--- Comment #4 from Johan Engelen <jbc.engelen at gmail.com> ---
Fixed in trunk.

Tested with LDC+LVMtrunk and D code:
import std.stdio;
import core.sys.posix.stdlib;

void main()
    void* result;
    writeln( posix_memalign(&result, 1, size_t.max), " (expected 22)");
    writeln( posix_memalign(&result, 32, size_t.max), " (expected 12)");
