1.5.5: Problem with Convert::ASN1 module and Perl 5.8.0


Hi,

Just to let people know that the Perl 5.8.0 binary distribution
installed with setup for the Cygwin 1.5.5 distribution has trouble
with the Convert::ASN1 package.  It wouldn't pass the "make test"
and the problem appeared to be Perl reporting something other than
Inf for POSIX::HUGE_VAL.  I reported a bug with the Convert::ASN1
package on CPAN.  For details, see Bug 4121 at
http://rt.cpan.org/NoAuth/Bug.html?id=4121.

An indicator of trouble is:

- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
$ perl -e 'use POSIX;print POSIX::HUGE_VAL, "\n";'
-6.77154008269804e-229
- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -

It should be something like:

- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
$ perl -e 'use POSIX;print POSIX::HUGE_VAL, "\n";'
Inf
- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -

It appears that the perl-5.8.0-5.tar.bz2 package that Cygwin 1.5.5
installs was compiled with GCC 3.2 while GCC 3.3.1 comes with
the 1.5.5 distribution.  Recompiling Perl 5.8.0 using the
perl-5.8.0-5-src.tar.bz2 source package resulted in Convert::ASN1
passing its tests.

Here's what the perl-5.8.0-5.tar.bz2 binary package from Cygwin 1.5.5
says:

I'm not sure what differences there are between the versions of
GCC used but I noticed that the lseeksize is different with
GCC 3.2 saying 4 while GCC 3.3.1 says 8.

I didn't try the perl-5.8.0-5.tar.bz2 binary package with Cygwin
1.3.22 which it was compiled under.  Nor did I try the
perl-5.8.1-2.tar.bz2 binary packae from Cygwin 1.5.5.

While the perl-5.8.0-5.tar.bz2 binary package does run under
Cygwin 1.5.5, other Perl modules may not fare as well.
