The answer is actually simple, the \n needs the multiline modifier, and thus the m needs to be part of the quote-like operator. The perl doc states: "This operator quotes (and possibly compiles) its STRING" (it seems 5.8 did not compile, but 5.10 does) I feel that it is rather not a perl bug, and that the modifiers need to be put on the qr{}. I do not quite see why this re needs to be multiline in the first place, but I have not touched that in the attached patch, that is ready to apply. (modification works in perl 5.6, 5.8, 5.10) Andreas
