Running the AdaCore internal test suite with -fgnat-encodings=minimal found a gdb crash. The bug is that GDB ends up with a typedef in ada_index_type, resulting in a NULL dereference. This crash can be reproduced using GCC 11 with the included test case. Tested on x86-64 Fedora 32. Because this is Ada-specific, and was already reviewed by Joel, I am going to check it in. 2021-04-30 Tom Tromey <tromey@adacore.com> * ada-lang.c (ada_index_type): Use ada_check_typedef. gdb/testsuite/ChangeLog 2021-04-30 Tom Tromey <tromey@adacore.com> * gdb.ada/enum_idx_packed/pck.ads (My_Enum, My_Array_Type) (Confused_Array): New types. * gdb.ada/enum_idx_packed/foo.adb (Confused_Array): New variable. * gdb.ada/enum_idx_packed.exp: Add new tests.
