What you can do is verify that the addresses are correctly read
You could try dumping the DWARF data if you have a tool that does that
on your system. Otherwise, you could check the assembly file where
prompt_for_continue is defined, and see if blocks indeed have
the correct relationship in terms of block addresses. It could be
the compiler emitting wrong debugging info, or the assembler/linker
toolchain that screws up. Or, possibly, GDB is reading the information
incorrectly, in which case, yes, you should be worried because that
might cause a fair amount of grief depending on what's going wrong.
I think this is unlikely, though.
