Good question. The PCRE code should be easy to read though, feel free to investigate? :)

I just like other people confirm that's a real bug :)

Sounds like something that should be added to the testsuite, anyway. Both of the problems...

I inadvertendly found out that replace1() succeed where replace() failed:

----8<----8<----8<----8<---- $ pike Pike v7.6 release 112 running Hilfe v3.5 (Incremental Pike Frontend)

string foo = " This is some text \0\0\0"; object r = Regexp.PCRE.Studied("[\W]*$"); r->replace1(foo, "");

(1) Result: " This is some text" ---->8---->8---->8---->8----

Should be a good start to narrow down the problem.
