This is a bug report for perl from [EMAIL PROTECTED],
generated with the help of perlbug 1.35 running under perl v5.8.5.
-----------------------------------------------------------------
Hello there. I think we've encountered a regression with bytecoding:
something that works in Perl 5.8.2 but not 5.8.5. I know that
B::Bytecode labels itself as highly experimental and risky, but I
mentioned this to Nicholas Clark (in a bar) and he said it was worth
reporting because even experimental and risky things shouldn't get worse
between releases.
These two lines are array1.pl:
my @a = (1);
$a[0];
We're using FreeBSD; I haven't been able to test this on any other OS.
This is an attempt to turn it into bytecode, saving it to the file byte;
it fails:
% perl5.8.5 -MO=Bytecode,-obyte array1.pl
Can't locate object method "ix" via package "UÃÃ
WVSÃ" at
/usr/local/lib/perl5/5.8.5/mach/B/Bytecode.pm line 575.
CHECK failed--call queue aborted.
But it succeeds if the filename used has at least 5 characters in it:
% perl5.8.5 -MO=Bytecode,-obyte2 array1.pl
array1.pl syntax OK
It also fails when writing to standard output:
% perl5.8.5 -MO=Bytecode array1.pl > byte2
Can't locate object method "ix" via package "UÃÃ
WVSÃ" at
/usr/local/lib/perl5/5.8.5/mach/B/Bytecode.pm line 575.
CHECK failed--call queue aborted.
This is array2.pl, which also fails to be bytecoded:
my @array = qw<a b c>;
my ($s1) = @array; # list assignment
my @copy = @array;
my ($s2) = shift @copy; # shift
my ($s3) = @array[0]; # slice
my ($s4) = $array[0]; # element
It's only the last line, accessing a single array element, of that file
which fails when trying to convert it into bytecode; with that line
removed everything works. Here's the error message, which is slightly
different from that with array1.pl, in that the package name is
readable:
% perl5.8.5 -MO=Bytecode,-obyte array2.pl
Can't locate object method "ix" via package "main" at
/usr/local/lib/perl5/5.8.5/mach/B/Bytecode.pm line 575.
CHECK failed--call queue aborted.
This time using a longer output filename doesn't seem to make it work.
None of these errors occur when using perl5.8.2 instead of perl5.8.5.
(I haven't tried 5.8.3 or 5.8.4.) I haven't spotted any significant
differences in their configuration. 5.8.2 was installed using this
package:
ftp://ftp.FreeBSD.org/pub/FreeBSD/ports/i386/packages-4.10-release/All/perl-5.8.2_5.tgz
I first tried 5.8.5 with this package:
ftp://ftp.FreeBSD.org/pub/FreeBSD/ports/i386/packages-4-stable/lang/perl-5.8.5.tgz
That differed from the 5.8.2 package in having 64-bit integer support,
so I then used the FreeBSD port for 5.8.5 and built it
WITHOUT_PERL-64BITINT to eliminate that from our inquiries. Below are
the configs for 5.8.2 and then for 5.8.5 (without 64-bit int).
Thanks for looking at this. Let me know if there's any more information
I can provide.
