| Subject: | Deep recursion triggered by calling ->string on a message from an IMAP4 mailbox opened rw |
I am accessing a mailbox using IMAP4 and pulling the entire message content to parse with a bounce processor. This works fine if the mailbox is opened read only, but fails if the mailbox is opened r/w.
If the mailbox is r/w the string method goes into deep recursion:-
Deep recursion on subroutine "Mail::Message::Head::string" at
/opt/perlbrew/perls/perl-5.20.0/lib/site_perl/5.20.0/Mail/Message/Head.pm line 26.
Attached test case - credentials stripped.
Environment is a perlbrew installation on Mac OS X 10.9.4 - modules are all pretty recent:-
