Hi all!
I have found a bug in the perl's debugger interface. It is exhibited with
perl -d, but a similar bug occurs in Devel::ebug.
See:
http://eskimo.shlomifish.org/bugs/perl/core/perl-minus-d-bug-1/
Download the tar.gz, unpack it and cd to its directory. Then
run "perl -Ilib -d d.pl". While in the debugger, press "n" a few times until
you reach line 61. At this point the display of the code of the current line
disappears. What happens is this:
<<<<<<<<<
main::(d.pl:57): my $prefix = catdir( qw( some prefix ) );
DB<1> n
main::(d.pl:58): $mb->prefix( $prefix );
DB<1> n
main::(d.pl:59): is( $mb->{properties}{prefix}, $prefix );
DB<1> n
ok 2
main::(d.pl:61):
DB<1> n
prefix=some/prefix
main::(d.pl:62):
DB<1>
>>>>>>>>>
Now, with perl-5.6.2 everything seems to work fine from what I tried. The link
above contains my perl -V outputs, both compiled from the perl distribution
with the default options.
I'm on Mandriva 2007 cooker.
There seems to be another bug with setting breakpoints in the file and
continuing there, but I hope they are related.
Regards,
Shlomi Fish
