As an FYI, upstream commit cde405a6b is what caused "perl -dt" to be required. Re-adding the lock prototype to the current perl5db.pl allows "perl -d" to at least start, but then the debugger errors out with "Modification of a read-only value attempted at .../perl5db.pl line 4129." which is this: # Save current single-step setting. $stack[-1] = $single; Cheers, James -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of "unsubscribe".
