Turns out it's a miscompilation bug as I was using the same set of C(XX)FLAGS
that work fine for those other languages.
Removing the -fomit-frame-pointer flag while leaving the rest unchanged (-O3

The repeated full ada bootstrap was successful at the same revision, using
identical flags and GNAT 5.4.0.
On the other hand, the failing build prints two warnings during the ada part:
g-debpoo.adb: In function

It's GNAT 5.4.0. OK, I'll try again.

Can you try again without --disable-bootstrap ?
What GCC exact version are you

Right, I definitely used the same setup a few days ago minus
--disable-bootstrap.

So without --disable-bootstrap, the build is successive?
If so then the bug is in GCC 5 rather than GCC 7.
