[Xenomai] rt task & stack overflow

[Johann Obermayr]

Hello,

is there a way to handle a stack overflow with a xenomai  rt_task ?

this example work for a standard linux
#define _XOPEN_SOURCE 700
#include <stdio.h>
#include <signal.h>
#include <unistd.h>
void handler(int sig)
{
    printf("stack overflow: %d\n", sig);
    _exit(1);
}
unsigned infinite_recursion(unsigned x) {
    return infinite_recursion(x)+1;
}
int main()
{
    static char stack[SIGSTKSZ];
    stack_t ss = {
        .ss_size = SIGSTKSZ,
        .ss_sp = stack,
    };
    struct sigaction sa = {
        .sa_handler = handler,
        .sa_flags = SA_ONSTACK
    };
    sigaltstack(&ss, 0);
    sigfillset(&sa.sa_mask);
    sigaction(SIGSEGV, &sa, 0);
    infinite_recursion(0);
}


thanks for help

regards
  Johann
