| Subject: | perl -d assert error when using !!perl/regexp '(?mix-s: ^\r? username: \s* $ )' |
YAML::XS gives assert error under perl -d, but not when running perl
with no debugger.
Save this program unto /tmp/aa:
--
use YAML::XS;
use Data::Dumper;
my $x = YAML::XS::LoadFile("/tmp/ax");
print Dumper $x;
--
Save this to file /tmp/ax:
--
x:
y:
z: !!perl/regexp '(?mix-s: ^\r? username: \s* $ )'
u: !!perl/regexp '(?mix-s: ^\r? Error \s? : )'
Under perl 5.12.2 run the program in the following way:
perl /tmp/aa
<it will run ok>
perl -d /tmp/aa
main::(/tmp/a3:6): my $x = YAML::XS::LoadFile("/tmp/ax");
