Subject: Geo::Calc::XS midpoint_to returns different results in debugger
Download (untitled) / with headers
text/plain 1.1k
The method midpoint_to returns different results when run with and without the debugger enabled. Without the debugger: $ perl run_with_debugger.pl $VAR1 = { 'lat' => '51.512438', 'lon' => '-0.133619' }; With the debugger: perl -d ~/run_with_debugger.pl Loading DB routines from perl5db.pl version 1.37 Editor support available. Enter h or 'h h' for help, or 'man perldebug' for more help. main::(/home/davidl/run_with_debugger.pl:14): 14: my $midpoint = Geo::Calc::XS->new(lat => 51.508348, lon => '-0.143719', units => 'm')->midpoint_to( 15: {lat => 51.516528, lon => '-0.123518'}); DB<1> c $VAR1 = { 'lat' => '51.5', 'lon' => '-0.1' }; Debugged program terminated. Use q to quit or R to restart, use o inhibit_exit to avoid stopping after program termination, h q, h R or h o to get additional info. The script is attached. I encountered this bug with Perl v5.16.3 on Linux compiled without threads. I also reproduced this bug with Ubuntu's packaged Perl v5.18.2.
Subject: run_with_debugger.pl
#!/usr/bin/env perl # Run this with "perl", and then with "perl -d", and you'll notice a bug that # the results are not the same! The latter trims the lat/long coordinates to # one decimal point. use strict; use warnings; use utf8; use Geo::Calc::XS; use Data::Dumper; my $midpoint = Geo::Calc::XS->new(lat => 51.508348, lon => '-0.143719', units => 'm')->midpoint_to( {lat => 51.516528, lon => '-0.123518'}); print Dumper($midpoint);
This has been fixed in 0.29.
