That shouldn't happen.
If you are on Windows, note that processes do not see the command
line as an array of arguments, but as a single string. It is then
the duty of the process to split up the string into individual
arguments. If the program lets the C runtime do it by reading
main's argc/argv, or uses CommandLineToArgvW (which is what C
runtimes usually use under the hood), things generally work ask
expected. However, some programs don't do that, and instead use
their own custom logic for parsing the command line string (such
as many built-in or standard DOS/Windows commands).
On POSIX, this can be caused if the program you're running is
itself running another program, and isn't constructing its
arguments correctly (e.g. it uses the system() function instead
of an exec* function).
