[Boost-users] libboost-regex-1.33.1 problem with regex_merge

Hi all, I have a problem with an application build with the current debian/etch libboost-regex lib. I am not sure if the problem results from an intended behaviour change of the regex lib or if its a bug of either the regex lib or the debian package. The following test app worked flawlessly with several older boost regex versions and I would like to understand why it doesn't work anymore using the lib from debian/etch. Do I have to adjust the invocation parameters of boost_merge for the current version? I do not unnecessarily want to force the users of my production apps to have to update their match patterns over dozens of cfg files from "(.*)" to "^(.*)$".
