It's similar to a recently fixed bug 31017: now Mail::Message::Field::Structured::parse() function can get into an infinite loop when parsing headers like these: Content-Type: application/octet-stream; name=xxxxxx[1].pif Content-Disposition: attachment; filename=xxxxxx[1].pif Thanks for looking into this issue. -Jason

Thanks. I have implemented two fixes: 1) when the character cannot be consumed by any rule, it will get forcefully removed... never an endless loop 2) [ and ] and now accepted as illegally unquoted characters, and I expect more to turn-up in the future.
