regex doesn't work: my error or bug?

[Gintaras]

It seems it is a bug or feature in the (older) library PCRE version that QM uses. I tested with current PCRE version and it works well.
Workaround 1: use + instead of *
Workaround 2: don't use (?<=')

Also, in you code the submatch argument is 2. Must be 0 or 1.
