Hi,

I'm trying to figure out why the following fails when compiled on amd64 with -m32:

	mmap(NULL, 0x70000, PROT_READ|PROT_WRITE|PROT_EXEC, MAP_ANON|MAP_PRIVATE, -1, 0);

It returns EINVAL. I looked around everywhere but I couldn't find where the EINVAL is coming from. The length argument doesn't really make any difference. At this point I'm thinking it's a bug...
