I think you already saw this thread (if not this is what you are looking for): |

To use valgrind on amd64 follow these steps: |
33 |
|
34 |
- emerge valgrind-3.5.0 (previous versions did not work) |
35 |
- valgrind prints out a message to reinstall libc (or was it glibc ?) with |
36 |
FEATURES=splitdebug - thats defintely needed |
37 |
- edit sage-valgrind in Sage's local/bin directory: remove "-- |
38 |
suppressions=..." option or point to this file (see thread above) and add -- |
39 |
trace-children=yes |
40 |
- start sage with "sage -valgrind" |
