Subroutine breakpoints should really be in the subroutine.

[rocky]

From perl #1726. Consider:

#!perl
use strict;
use warnings;
sub problem {
    $SIG{__DIE__} = sub {
    die "<b problem> will set a break point here.\n"
    };
    warn "This line will run even if you enter <c problem>.\n";
}

problem();
exit(0);

(This is example/sub-brkpt-bug.pl in git and this may be related to a Module::Signature bug in example/signature.pl)

Setting a breakpoint on problem sets the breakpoint on the "die" statement which is wrong. It so happens that the first breakable line is the line after that which contains };.

Possibly the best fix is to run the breakpoint from &DB::sub rather than try to convert the subroutine into a line number.

This is somewhat fixed now. There may be lingering problems though.
