A critical bug in boost::function (1.34.1) has been reported on the boost newspage. There also exists a fix in the form of two new header files. Additionally I have discovered an include omission in boost::regex which prevents gcc-4.3 from building translation units that use the regex library. I'm providing a new ebuild with the two patches here. The missing include in boost::regex is probably not the only one in boost but it is nevertheless worth fixing.
Created attachment 139057 [details] New ebuild
Created attachment 139058 [details] Function patch
Created attachment 139059 [details] Regex include patch
Fixed in CVS as 1.34.1-r1. Thanks!
