Re^3: Debugger line numbering anomaly

again:

is the problem reproducible if you copy the code from this thread?
did you include warn to see if the compilation recorded the right line-numbers?

and

can you narrow down which code-line is starting the problem?

update

There are internal arrays which hold all parsed lines of the debugger, you could check there if the debugger got it right.

perldebguts :

Each array @{"_<$filename"} holds the lines of $filename for a file compiled by Perl.

First, I compared (in the programmer's text editor Epsilon) perl5db.pl v 1.5.1 and 1.5.3. Only a few differences; none seems significant to this issue. So I copied the 1.5.3 version to /usr/share/perl/5.26/perl5db.pl on the Xubuntu machine. Same (wrong) debug behavior as with the original 1.5.1 version. Further, the debug command "x @{$main::{'_<t6.pl'}}" is also missing the (original) line 5. This suggests (so far) that it's a Perl 5.26 bug, and not a perl5db.pl bug. Still exploring ... -- Lee	[reply]

well, good luck ignoring the other stuff I asked you to check. Cheers Rolf _{(addicted to the Perl Programming Language :) Wikisyntax for the Monastery FootballPerl is like chess, only without the dice}	[reply]

How is db_tst.pl different from what I posted? No, the script doesn't have Windows/DOS line endings. If it did, it wouldn't matter to Linux, if I call it via 'perl script.pl'. But it clearly runs fine on Linux (at least my Xubuntu and Debian installations). And the debugger issues no warnings. What kind of warning could I insert that would help? It's not a runtime problem; it's a problem of the debugger missing a line, and so subsequent line numbers are off by one. I note in the perl5db.pl POD text: `@dbline Local alias to the magical line array, "@{$main::{'_<'.$filename}}" , supplied by the Perl interpreter to the debugger. Contains the source +.` [download] That's pretty clear that the Perl 5.26.1 interpreter is providing a buggered line array. I don't know how to follow up with that, except to upgrade to something newer. -- Lee	[reply] [d/l]
