This patch fixes a bug where if a parent library package contains a with
clause that mentions a child of that same parent package, then gnat can
crash if the parent package is compiled with the -gnatR2 switch.
Tested on x86_64-pc-linux-gnu, committed on trunk
gcc/ada/
* repinfo.adb (List_Entities): The code was assuming that if we
encounter a package in the current scope, then it must be
a (physically) nested package. That was wrong, because it could
be a child package. Avoid recursing into child packages; they
have not been annotated with representation information, and
-gnatR2 queries that information.diff --git a/gcc/ada/repinfo.adb b/gcc/ada/repinfo.adb
