    SubjectNO core dump ?
    Everybody is happy if no core dump occurs. Ok, I'm not happy.
    I have written a program and made some mistakes. The program
    crashes _Segmentation fault_ - but no core dump.

    Therefore I tested this one:

    int main(unsigned int argc, char **argv)
    {
    char *p;

    p = 0;
    *p = 0;
    }

    compiled by /usr/bin/gcc -v -g -o x x.c

    Reading specs from /usr/lib/gcc-lib/i486-linux/2.7.2/specs
    gcc version 2.7.2

    ldd x reports
    libc.so.5 => /lib/lic.so.5.3.12

    ./x works with

    Segmentation fault

    but no CORE DUMP.

    Any ideas ?

    BTW kernel 1.3.97 (working without problems).

    Thanks Peter
