I've just hit this issue with 14.04 Trusty amd64 and like Adam, "valgrind ls" works but "valgrind ./a.out" for the (simple) C++ program I was working with (that demonstrates layout of objects in memory) induces the same "strlen" failure message.
I tried to reproduce a minimal test case and couldn't and then realised the reason for the message: At one point I'd built the binary for 32-bit architecture using g++ -m32 .... Building for native 64-bit doesn't induce the issue, so the problem appears to lie in the multilib support. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1247026 Title: valgrind does not work on amd64 (strlen missing) To manage notifications about this bug go to: https://bugs.launchpad.net/valgrind/+bug/1247026/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
