While I'll agree that something looks fishy, we can't tell what. You don't actually know what the correct values are. You can guess that they're wrong, based on the curious value of RA that you get from that frame. But you'd want to print the correct values from foo itself to verify. You'd want to use objdump -Wf to examine the unwind info of the other functions in the call chain to see which one might be incorrect. You may have to combine this with examining register contents while stopped inside of a debugger. r~
