Debugger for GNAT

["markp" <markwork66@yahoo.com>]

We are currently using the GPS debugger for our GNAT Ada applications.
We feel it is not a very robust debugger, although that could be our
limited experience with it. For example, we would to be able to break
on any exceptions and view the offending line in the debugger and trace
to the source. Also, we would like to be able to set breakpoints in
tasks while the program is running without stopping everything, i.e.
stopping a single task.

Are there any other debuggers out the to debug our GNAT Ada?

Thank you.
