My favorite is that the PCRE library (PCRE=Perl Compatible Regular 
Expressions) is not actually Perl compatible. At least, not with Perl 5; 
maybe it was compatible with an archaic version.

The one part of regex that i still don't quite get is lookarounds. 
Whenever i have to do one of those i reach for some reference books to 
figure it out just well enough to make it work. And when i see one, i 
recognize the syntax just well enough that i know what it is and know to 
go grab my references to help figure it out. Fortunately, not many 
people use lookarounds. I don't use them very often; *usually* when i 
think i need one i realize that the problem i'm trying to solve would be 
done more efficiently or more maintainably with a mix of normal code and 
a less complicated regex.
