Hi,
I am running the 3.4.0 release on a 64 bit Ubuntu box. While running the
linbox (linalg.org) test suite under ptr-check I am seeing the following:
mabsh...@sage:~/build/linbox-testing/linbox-svn3066/tests/foo$
~/build/eMPIRe/sage-3.2.3.final/local/bin/valgrind --tool=ex

Note: see also the FAQ.txt in the source distribution.
It contains workarounds to several common problems.
If that doesn't help, please report this bug to: www.valgrind.org
In the bug report, send all the above text, the valgrind
version, and what Linux distro you are using. Thanks.
Thoughts?
Cheers,
Michael
