--- Comment #1 from Thomas Koenig <tkoenig at gcc dot gnu.org> ---
I am AFK at the moment, so I can not dig deeply right now.

However, the description raises one important flag: The vararg call.

There is no way that a vararg call to a Fortran procedure can be valid.
POWER just happens to have an ABI which exposes this.

The change in question was a fix for an ABI violation on POWER for
valid code, BTW.

If there is anything more, please let me know, otherwise I would resolve
this as INVALID and advise the authirs to fix the code.
