To get that exception you're going to have a controlled type somewhere,
very likely one of yours, and very likely to be found at
device_type_pkg.ads:115 (I'm guessing, some ancestor in the
Device_Class_Type tree? do you have some reason for naming this type
instead of just using Device'Class or (ugh) Device_Type'Class?).

At line 694 you are overwriting whatever was at
Device_Array(Device.Device_Id); full explanation of what this involves
starting at ARM 7.6(17).

Any unhandled exception raised in Initialize (?), Adjust (?) or Finalize
is going to be converted to PE. See ARM 7.6.1(14) ff.

You could always use the debugger and break on exceptions (e.g "catch
exception program_error").
