Subject: bug#65516: 30.0.50; Edebug behavior of signaling errors in &or
Date: Fri, 25 Aug 2023 08:28:26 +0200

This is a followup to bug#65344, which see.

When Edebug matches a debug spec

  (&or (... def-form)
       (...))

and the form matched against is not something def-form matches,
an invalid-read-error is signaled, regardless of the context in which
def-form appears.  That means the second sub-clause of the &or never
gets a chance to match.

This is not limited to def-form and not limited to &or (think
&not, for example).
