--- Comment #2 from Jeffrey A. Law <law at redhat dot com> ---
I see what's happening.

It's specific to cases where a function needs a probing loop, uses all the
argument passing registers, but no callee saved registers.

At first glance it looks like both stack-clash and stack-check are affected. 
No surprise since they have the same basic structure for handling large frames.
