Transaction: Ticket created by dave_clarke@merck.com Queue: PAR Subject: Suspected buffer overflow while running executable made by Par::Packer Broken in: (no value) Severity: (no value) Owner: Nobody Requestors: dave_clarke@merck.com Status: new Ticket <URL: http://rt.cpan.org/Ticket/Display.html?id=39233 > I have encountered an error while running an executable made by Par::Packer. It occurs as part of a regexp pattern match. The error has been narrowed down to this snippet of code (problem bolded): $_ = q[TEXT="some_very_large_text_to_be_extracted_between_double_quotes"]; my $rQStr = qr/"((?:""|[^"])*)"/; # String between double quotes (") my $key = 'TEXT'; if (m/${key}=${rQStr}/) { $_ = $1; $_ at the start of the pattern match contains a large string (> 7000) characters. The perl script executes flawlessly, and has been in production for over a year. I recently distributed this script and associated modules to other users using Par::Packer. The .exe generated by Par::Packer works for strings up to 7261 characters, but fails silently at 7262 characters between the quotes. In other words, the .exe just exits w/o issuing any kind of error msg.
