This looks like language should be ada...

> The current source language is "auto; currently ada".

... and part of gdb thought so as well...

It would be interesting to see the contents of 'func'.

A small, self-contained example program might also be good, along
with the command line you used to build it.  I was wondering if perhaps
you were using stabs instead of dwarf, for instance.

The test suite has some tests of 'catch exception', and for me this
works fine as long as I have an Ada runtime with the necessary debuginfo.
