Public bug reported:
valgrind works as expected on 64-bit binaries, when using a x86-64 installation...
[icculus at taise ~]$ cat hello.c

int main(void) { printf("hello.\n"); return 0; }
[icculus at taise ~]$ gcc -m64 -o hello hello.c

Please note that "lib6-dbg" is installed on this system...

libc6-dbg is already the newest version.

This worked with 32-bit binaries in the past (perhaps as recently as 11.04, but I can't say for certain).
This is happening on a fresh 11.04 x86-64 desktop install, default
Ubuntu (not Kubuntu, etc). There are some non-default packages
installed, like multilib-gcc, as you can tell by the "gcc -m32" command
line working, but I don't think these are causing issues.
Let me know if you need more information.
