I recently upgraded to Snow Leopard, and tried to reinstall the percona build of MySQL. It led to these errors. I’ve seen others have trouble with gcc v4.1 and greater. I’m currently on gcc 4.2.1.

It looks like this is related to the bug report at launchpad:  
[URL][https://bugs.launchpad.net/percona-patches/+bug/340273[/URL]](https://bugs.launchpad.net/percona-patches/+bug/340273%5B/URL%5D)

Any help would be appreciated.
