Thanks to Dave for getting the strace patches. The gdb64 package and strace with 64-bit native binary packages should be showing up in Debian soon. For those that can't wait, here's the packages I've built. You need the lib64readline4 package for gdb64. The strace package contains the 32-bit and 64-bit versions.
