Hi.
I know the root cause of the failure and will send a patch soon
to the mailing list.

There's an obvious patch that I'm going to install. Note that
order of function call evaluation in a function call is undefined.
It's a similar issue we had some time ago in IPA VRP streaming.
Patch can bootstrap on x86_64-linux-gnu and survives regression tests.
Thanks,
Martin
