GDB Debugging Problem

I have added some code in my file.
I have created executable rpm file of our code and also I have created debuginfo and debugsource files and installed all three.
But when I debug in gdb I see the the code changes in soucre file. But the break point does not hit at that place as if it did not find the added code changes.
Through gdb command like info source and show dir. etc I see the code changes but breakpoints is not setting on that.
What might be the issue and how to get rid of this issue?

It sounds like gdb is accessing your new source files but still using the old executable?
