gdb 6.5 on AIX 5.3 not hitting breakpoints

gdb 6.5 on AIX 5.3 not hitting breakpoints

[Jesse Marlin]

I have built gdb-6.5 on AIX 5.3 and have noticed that it is not hitting 
breakpoints.  Is this a known problem and if so is there any workaround?

Thanks!

I've had only little time to work on AIX lately, but it is still
expected to work well. So this is definitely not a known problem.
I'll take a quick look tonight to see if breakpoints work for me.

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.
        (gdb) run
        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).

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 6.5.50.20061115.  I tried with a simple 
program and it worked:

--------------------------
(gdb) br main
Breakpoint 1 at 0x100003f4: file errno.c, line 11.
(gdb) run
Starting program: /home/cgi/errno_aix

Breakpoint 1, main (argc=1, argv=0x2ff20084) at errno.c:11
11              sscanf (argv[1], "%d", &err);
(gdb)
--------------------------


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.
(gdb) run
Starting program: /u01/obj/dcs/misc/bin/cgr_heartbeat_utl
Breakpoint 1 at 0x100000a90: file cgr_heartbeat_utl.c, line 223.
HEARTBEAT>
--------------------------

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?
