Spurious linebreak in non-record output

Hello,

sorry to be a pain, but here is another case of the spurious linebreak.
Environment is OpenVMS IA64 8.3-1H1, Perl 5.12.3 with useperlio defined.

I am using Perl with the CGI module to dynamically create a medium sized 
table (a few hundered rows and 6 columns). The script works fine on 
Perl 5.8.8 on OpenVMS Alpha.

When accessing the script via a webserver, spurious linebreaks are inserted 
into the table, causing garbled output (e.g. a <td ends up as <t\nd, which also
a forgiving parser will not process correctly). Running the same script in debug mode and sending the output to a file does <<not>> show the spurious linebreaks.

Shorter tables generated by the same script work fine also with 5.12.3 .

I've already changed the script to write the table one row at the time to the CGI output, but that this not resolve the issue.

Any ideas and/or hope that this will be resolved with the soon to be released 
5.14?

Greetings, Martin
