Do you build only PowerPC64le with "-gnatn -g -O3" or other platforms?  If the
latter, do they still build correctly at the same revision?  I'm trying to find
out whether this was introduced by the only Ada patch in the range:

2017-05-22  Eric Botcazou  <ebotcazou@adacore.com>

        * gcc-interface/decl.c (gnat_to_gnu_entity): Skip regular processing
        for Itypes that are E_Access_Subtype.
        <E_Access_Subtype>: Use the DECL of the base type directly.

Btw, can you post a backtrace?
