I think you already saw this thread (if not this is what you are looking fo= r): http://groups.google.com/group/sage- devel/browse_thread/thread/cd8005be927fc896 To use valgrind on amd64 follow these steps: =2D emerge valgrind-3.5.0 (previous versions did not work) =2D valgrind prints out a message to reinstall libc (or was it glibc ?) wit= h=20 =46EATURES=3Dsplitdebug - thats defintely needed =2D edit sage-valgrind in Sage's local/bin directory: remove "-- suppressions=3D..." option or point to this file (see thread above) and add= -- trace-children=3Dyes =2D start sage with "sage -valgrind" >=20 > Steve Christopher
