Well, it's nothing to do with nvi. If you aren't in a directory you have
write permission for, the kernel can't write a core file for you. Try it in
/tmp, you should find it can dump core there.
Try writing a simple program which just calls abort() - you will see it
exhibits the same behaviour.
=== begin code
#include <stdlib.h>
int
main(void) {
abort();
exit(EXIT_FAILURE);
}
=== end code
ben@strontium:~/tmp$ ./a.out
zsh: abort (core dumped) ./a.out
ben@strontium:~/tmp$ cd /
ben@strontium:/$ ~/tmp/a.out
zsh: abort /home/ben/tmp/a.out
