Subject: [PATCH] ada: GNAT-LLVM compiler crash on container aggregates with
iterators
Recent fixes for container aggregates with iterated element associations
exposed a latent bug with loops that are wrapped in blocks, where the loop
entity's scope was not adjusted to reflect the new enclosing block scope.
gcc/ada/
* sem_ch5.adb (Analyze_Loop_Statement.Wrap_Loop_Statement): Remove
the loop Entity_Id from its old scope and insert it in the new
block scope that wraps it.
