If you're on Linux, GDB 7.12 has Rust support. Fedora hasn't packaged that yet, but I did this to get a fresh GDB that I can run from ~/gdb/bin:
sudo dnf builddep binutils gdb mkdir ~/gdb cd ~/gdb git clone git://sourceware.org/git/binutils-gdb.git mkdir build cd build ../binutils-gdb/configure --prefix=$HOME/gdb make -j8 make install (These instructions probably belong someplace else...)
