The problem is, I think, that the GNAT RTL (libgnat, libgnarl) isn't
compiled with debug (-g), so there are no symbols available to
interpret the traceback.

This was certainly true with VxWorks static libraries a while back,
while we were compiling our own we used -g which allowed us to use
vxaddr2line and trace into the RTS. Since we changed to using the
standard RTS + changes compiled using powerpc-wrs-vxworks-gnatmake -a
I can't say we've missed the facility.

I don't know whether you can debug into or get traceback from inside a
dynamic library. Probably depends on the target OS.
