--- Comment #3 from Markus Trippelsdorf <trippels at gcc dot gnu.org> ---
Normally, you could enable verbose output with something like "make VERBOSE=1".
And then add --save-temps to the failing gcc invocation by hand
(and also post the full invocation here).

Thanks. I can reproduce the issue with trunk:
