You could just run your code in the debugger and do this when you find a warning you want to stop on:

$DB::single = 1;

    Thanks, that saves the action of setting a breakpoint.

    But even better, I could shift the signal handler code into the debugger initialization file .perldb. Then I do not have to modify the original source code. Works great!

    This is the content of file .perldb (place it in the current or in the home directory):

    sub afterinit { $::SIG{'__WARN__'} = sub { my $warning = shift; if ( $warning =~ m{\s at \s \S+ \s line \s \d+ \. $}xms ) { $DB::single = 1; # debugger stops here automatically } warn $warning; }; print "sigwarn handler installed!\n"; return; }
