I wish this help you Blocking the SIGWINCH fixed the problem, as suggested by @KarstenKoop's comment.
Checking the signals being listened by processes according to unix.stackexchange.com/q/85364/114939, we can see that no processes blocks the signal SIGWINCH, even the processes lauched by system().

Python : fork and exec a process to run on different terminal

To fix this issue If you want "real" (pseudo-;-) terminals, and are using X11 (almost every GUI interface on Linux does;-), you could exec xterm -e python node.py instead of just python node.py -- substitute for xterm whatever terminal emulator program you prefer, of course (I'm sure they all have command-line switches equivalent to good old xterm's -e, to specify what program they should run!-).

I wish this helpful for you The issue was with the improper closing of the already opened file descriptors. Some had to be closed, which I hadnt done. So the process used to keep waiting for input.

help you fix your problem The shell i'm writing needs to execute a program given to it by the user. Here's the very shortened simplified version of my program , Here's a simple, readable solution:
pid_t parent = getpid();
pid_t pid = fork();

if (pid == -1)
{
    // error, failed to fork()
} 
else if (pid > 0)
{
    int status;
    waitpid(pid, &status, 0);
}
else 
{
    // we are the child
    execve(...);
    _exit(EXIT_FAILURE);   // exec never returns
}

OS X: c++ xcode ncurses resize terminal

Hope that helps ncurses responds to window-resizing events, i.e., SIGWINCH. It does not resize the terminal (see manual page for resizeterm).
xterm and some other terminal emulators respond to an escape sequence which tells it to resize. You can exercise that with the utility program resize, e.g.,
resize -s 40 80
