Hi, Mario,

This happens only with C++ programs?  Can you provide details of how they are linked?  A common problem is accidentally 
linking against more than one of the C++ run-time libraries, which causes all sorts of strange issues.

Cheers,

Christian

I think it is because you directly work with terminal. i.e. making fcntl 
calls on stdin. Because destructor is not running it leaves it some 
weird state,
and qconn cannot recover (leaved block on pty).

Hmm, I created a small example, but I cannot run or debug it... It 
always fails to read if I do fcntl, if not it runs fine...

#include <stdlib.h>
#include <stdio.h>
#include <unistd.h>
#include <fcntl.h>

int main(int argc, char *argv[]) {
    int n;
    int ch = 0;
    int rc = 0;

    printf("Welcome to the QNX Momentics IDE\n");

    rc = fcntl(STDIN_FILENO, F_SETFL, O_NONBLOCK);
    if (rc != 0) {
        perror("fcntl failed");
    }

    printf("enter text:\n");
    /* read the outstanding chars, one by one, until newline or no more */
    n = read(STDIN_FILENO, &ch, 1);
    if (n>=0) {
        printf("char -> %c\n",ch);
    } else {
        perror("read failed");
    }
    printf("done\n");
    return EXIT_SUCCESS;
}

I get
