Ignore this patch: this failure is indeed caused by it.
(as per IRC)

To summarize: test_SuspendProcessState() arranges for ExitProcess() to 
be called by the child process but in the x86_64 case it does not 
specify the exit code to use (no exit_code field is set on the stack).

So the child process exit code is the result of a race between the 
parent's TerminateProcess() call (0 exit code) and the child 
ExitProcess() call (random exit code).

In the 32 bit case the exit code is set to 0 in the child too 
(remote_rop_chain.exit_code) so there is no issue.

Setting the child process exit code in the 64 bit case is presumably 
tricky and not the point of the test so the exit code should just be 
ignored.

I'll resubmit the patch.
