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

ldd x reports => /lib/

./x works with

Segmentation fault

but no CORE DUMP.

Any ideas ?

BTW kernel 1.3.97 (working without problems).

Thanks Peter
