conditionnal -> conditional

FYI: adding the test's name ("insert catchpoint [...]") is always
completely fine. It is not absolutely necessary in this case,
because the default test name is the command being sent, and
since it is unique in this case, it can be used as such.

Did you mean "assertions" instead of "handlers"?

This seems unused. You could have used it in catchpoint_msg, but
you're already checking which sound line we're stopping on, so...

> +set catchpoint_msg \

> +  "Catchpoint $decimal, failed assertion at $hex in bla \\\(\\\).*at .*bla.adb:$decimal"

If it were me, I would check the contents of the entire line of
source code, rather than just "STOP", as it makes it clearer what
the intent is. But feel free to ignore,  this is good enough.

No further comment past this point.
