[perl #60872] Perldiag doesn't contain "No such hook"

# New Ticket Created by  hansmu@x4all.nl

This is a bug report for perl from hansmu@x4all.nl,
generated with the help of perlbug 1.35 running under perl v5.8.6.


-----------------------------------------------------------------
[Please enter your report here]

Perldiag does not explain what the message "No such hook" means.

This can be reproduced by:

	perl -Mdiagnostics -e '$SIG{__FOO__} = sub {};'

This reports:

Uncaught exception from user code:
        No such hook: __FOO__ at -e line 1.
 at -e line 1

Notice how diagnostics thinks this exception is thrown by user code,
when in fact the %SIG is part of the core.
