This is a bug report for perl from dmitry@karasik.eu.org,
generated with the help of perlbug 1.41 running under perl 5.29.2.
-----------------------------------------------------------------
[Please describe your issue here]
ce6f496d720f6206455628425320badd95b07372 changed float/double formatting
from strtoflt128 to Perl_strtod, which had a nasty side effect when running
under non-english locales (or I suspect with locales that use comma for decimal point)
together with GTK or any other library that calls setlocale() itself.
The test for this is rather elaborate, so I'm attaching a localebug module
that tests for it when run 'make test'. One needs the following (for Ubuntu, for
example):
* apt-get install libgtk2.0-dev (gtk development files)
* cpan ExtUtils::PkgConfig
* locale-gen de_DE.UTF-8 && update-locale (tests need de_DE.UTF-8)
When running with a faulty configuration, the core issue is basically this:
my $s = sprintf "%s", 4.9999;
die "bug:$s" if $s !~ /^4[,.]9999$/;
which prints just "4".
The module attached can also be found at http://karasik.eu.org/misc/localebug-1.00.tar.gz
