Nothing. This is the proper way to build your program. But the compiler
you are using is producing incomplete debugging information. I get
the proper result when I use GNAT Pro (the compiler supported by Ada
Core).

This is confirmed by:

This confirms that the debugging info is incomplete. The debugger
cannot guess that the "1-byte integer" is a character, and thus
prints the array as an array rather than a string.
