A user at AdaCore found a case where assignment to a nested packed structure would fail. The bug is that ada_value_primitive_field doesn't account for the situation where a field is not packed relative to its containing structure, but where the structure itself is packed in its parent. gdb/ChangeLog 2019-05-01 Tom Tromey <tromey@adacore.com> * ada-lang.c (ada_value_primitive_field): Treat more fields as bitfields. gdb/testsuite/ChangeLog 2019-05-01 Tom Tromey <tromey@adacore.com> * gdb.ada/packed_array_assign/aggregates.ads (Nested_Packed): New record. (NPR): New variable. * gdb.ada/packed_array_assign.exp: Add nested packed assignment test.
