This gcc command causes a segmentation fault. The pre-processed file this
output says to include in the bug report is far too large (675K) to inline in
this report, and I see no way to attach it to the report. Let me know if you
want me to email it or something.

This only fails with the C front-end, here is a testcase that also compiles
with the C++ front-end but only fails with the C front-end:
static inline __attribute__((always_inline)) void ip_finish_output2(){}
void ip_fragment(void (*)(void));
static inline __attribute__((always_inline)) void ip_finish_output()
{
ip_fragment(ip_finish_output2);
ip_finish_output2();
}
void ip_mc_output()
{
ip_finish_output();
}
void ip_output()
{
ip_finish_output();
}

(In reply to comment #3)

> with the C++ front-end but only fails with the C front-end:
But I think that is only because the C++ front-end is always unit-at-a-time as
the C testcase passes when using -funit-at-a-time.
