Really not sure about this. It's reasonable to do e.g., alias gs="gdbserver --wrapper=/whatever/wrapper --" (or the equivalent wrapper shell script that execs gdbserver) and then always start that instead of gdbserver: sometimes: $ gs :9999 PROGRAM othertimes: $ gs --attach :9999 $pid but after the patch, the latter errors out. Plus, one can combine --attach and --multi, which means that the wrapper would still apply to processes spawned after connecting. Thanks, Pedro Alves
