Bug ID: 213696
Summary: gdb ignores breakpoints
Product: Base System
Version: 11.0-STABLE
Hardware: amd64
OS: Any
Status: New
Severity: Affects Only Me
Priority: ---
Component: bin

Hello,
On FreeBSD 11-Release, gdb breakpoints do not seem to work.
The following program:
#include <stdio.h>
#include <stdlib.h>
int main (int argc, char **argv) {
fprintf (stderr, "hello bsd\n");
fprintf (stderr, "bye bsd\n");
}
compiled as follows:
cc -g -O0 gm2.c -o gm2
$ gdb gm2

(gdb) break main
Breakpoint 1 at 0x4007a9: file gm2.c, line 5.
(gdb) run
Starting program: /usr/home/gmarthe/c/gm2
hello bsd
bye bsd
Program exited normally.
You can't do that without a process to debug.
(gdb) quit
I have the same results on FreeBSD-CURRENT, to be expected as that is the same
version of gdb.
I'm new to BSD and so maybe I'm missing something here. I would expect this to
run as it does under Linux - see below:
$ gdb gm2
