Usually the .gdbinit lives where the program is built.

Without gud-chdir-before-run you need to M-x cd to the build directory
*before* invoking M-x gdb, which would clobber default-directory for the
current buffer.

Alternatively there should be an easy way to do M-x in a different
default-directory then the one from the current buffer.
