I think I have an idea, now. It is similar to what we need to do
in the "catch exception" testcases, where we start the program
in order to be certain that we can find the symbols from the GNAT
runtime. On Fedora, and I suspect may other distros, the default
for gnatmake is to like against the shared libgnat, whereas the
gnatmake I use links against the static libgnat - this is why
I didn't see that omission. Can you try the attached?
gdb/ChangeLog:
* gdb.ada/info_exc.exp: Start inferior before starting
the "info exceptions" tests.
* gdb.ada/mi_exc_info.exp: Start inferior before starting
the "-info-ada-exceptions" tests.
Tested on x86_64-linux.

Subject: [PATCH] Start inferior before running test listing Ada exceptions.
This patch fixes some spurious failures when the inferior is linked
against the shared version of libgnat by default, as appears to be
the case on many GNU/Linux distributions. When that happens, we have
to start the program in order to ensure that the GNAT runtime is
mapped to memory, in order for us to find the standard exceptions
(defined within the runtime). Otherwise, they will not be shown,
as expected, by the debugger.
gdb/ChangeLog:
* gdb.ada/info_exc.exp: Start inferior before starting
the "info exceptions" tests.
* gdb.ada/mi_exc_info.exp: Start inferior before starting
the "-info-ada-exceptions" tests.
