Is it possible to limit the amount of memory a process consumes from the command line and eventually automatically kill the process if it tries to overpass this limit?

Something like

MaxRam -4GB ./MyProcess args

For your information, I am on Mac OSX Version 10.11.3.

    On Linux there is a ulimit command which allows control over the resources "on systems that allow such control" (help ulimit or man bash for information), but I don't know if the limit extends to any or all subprocesses launched; if not OSX may have system programs to specify the limits on a program as it is run, but this would not be a bash internal command.

On Linux you'd use:

prlimit -m4000000000 ./MyProcess args

Note that -m limits the RSS, use -v to limit virtual memory.
