The assembly window in Lazarus is shown when no backtrace line is
available to point the cursor in, so open callstack "View -> Debug ->
Callstack" and you will see that there is no available backtrace,
maybe except the fpc sources without debug information (you will see
some, usually 3, function names). The backtrace is often damaged when
memory corruption happends and usually calling a non initialized
object and not nil of course (as freed objects with heaptrc are
signaled with a magic number).
