I have never seen this behavior with gdb with any other unices, but this
is the first time we have run it on AIX.
I built the daily snapshot gdb 126.96.36.19961115. I tried with a simple
program and it worked:
(gdb) br main
Breakpoint 1 at 0x100003f4: file errno.c, line 11.
Starting program: /home/cgi/errno_aix
Breakpoint 1, main (argc=1, argv=0x2ff20084) at errno.c:11
11 sscanf (argv, "%d", &err);
Then I tried with one of our more complicated programs and I see the
behavior with it ignoring the breakpoints:
(gdb) br main
Breakpoint 1 at 0x10000a90: file cgr_heartbeat_utl.c, line 223.
Starting program: /u01/obj/dcs/misc/bin/cgr_heartbeat_utl
Breakpoint 1 at 0x100000a90: file cgr_heartbeat_utl.c, line 223.
I am wondering if it isn't some weird linker options that are screwing
it up or maybe we are missing some linker options. Any ideas?

As far as I can tell, appart from an unexpected warnings about the OS
ABI which I will try to investigate when I have some time, the HEAD
debugger from CVS seems to be working fine:
(gdb) b break_me
Breakpoint 1 at 0x100003e4: file foo.c, line 6.
Starting program: /home/brobecke/test/ex/foo
Breakpoint 1, break_me () at foo.c:6
6 printf ("Hello world\n");
I suggest trying the debugger from CVS, and if that doesn't work,
then maybe trying to post more information about what compiler you
used (I assumed GCC), which version, and provide a complete example
that demonstrates the problem (sources and compilation switches that
you used to build the example).
