[Boost-users] [Regex] anyone seeing performance dip w/regex matching moving from 1.47->1.48 w/gcc?

Hi, I just pulled down boost regex 1.48 and built it with gcc 4.3 on CentOS 5.5. My internal regex performance tests are showing > 30% performance degradation between versions 1.47 and 1.48. I wanted to ask if anyone else has seen anything like this? We've been using the same makefile to built boost regex for a long time, and we haven't converted to bjam. So I am wondering if this could be due to our particular build environment? TIA, Gary Protected by Websense Hosted Email Security -- www.websense.com
