[CentOS] Problem with gdb or maybe gcc

I have CentOS 5.7. Before the last updates, when I ran gdb with a 
program name gave a breakpoint and then typed run it would stop on that 
breakpoint. Now it prints the message "Warning: no loadable sections in 
added symbol file." It then just runs the program without stopping. What 
could have changed? Are there some flags that need to be set when 
invoking gcc?

Thanks,
John
