Fair enough, I was just thinking that the other main thing to happen before startup is .init c-tors running. >>> How can I link to a dll directly?

Sorry, I haven't been clear; that was only relevant to the theoretical case that you were invoking the linker directly.

Hmmm, or perhaps it's a real error that affects one of your target programs differently than the other. > gdb: unknown target exception 0xc0000135 at 0x7c974ed1 That's STATUS_DLL_NOT_FOUND. Interesting.
