        <pre>If we use dsym/dwarf as a debug info and a symbol is removed from the object
file during linking (because it is unused) then LLDB correctly reports an error
when the user want to set a breakpoint on it.

In case of dwo debug info the symbol will be still available in the *.dwo file
as it isn't modified by the linker when it removed the unused function. Because
of it LLDB will set a breakpoint at address 0x0 (the address stored at the
location where the symbol address should be stored in the executable) instead
of reporting an error.

For a test case see: DeadStripTestCase.test</pre>
