Eric Botcazou <ebotcazou at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- Status|UNCONFIRMED |WAITING Last reconfirmed| |2017-05-24 Ever confirmed|0 |1 --- Comment #1 from Eric Botcazou <ebotcazou at gcc dot gnu.org> --- 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 <ebotca...@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. --- Comment #2 from Eric Botcazou <ebotcazou at gcc dot gnu.org> --- Btw, can you post a backtrace?
