From: Eric Botcazou <ebotca...@adacore.com>
This occurs when the component is part of a discriminated type and its
offset depends on a discriminant, the problem being that the front-end
generates an incomplete Bit_Position attribute reference.
gcc/ada/
* exp_pakd.adb (Get_Base_And_Bit_Offset): Use the full component
reference instead of just the selector name for 'Bit_Position.
Tested on x86_64-pc-linux-gnu, committed on master.
