[COMMITTED] ada: Crash on C++ constructor of private type
Commit Message
From: Javier Miranda <miranda@adacore.com>
The compiler crashes compiling a function that has pragma
CPP_constructor when its return type is a private type.
gcc/ada/
* sem_util.adb
(Is_CPP_Constructor_Call): Add missing support for calls to
functions returning a private type.
Tested on x86_64-pc-linux-gnu, committed on master.
