Re: gdb 6.5 on AIX 5.3 not hitting breakpoints

[Jesse Marlin <jesse.marlin@intec.us>]

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?
