It's an unfortunate side effect of the way dumper works.  The dumping
process is paused waiting for a debugger (in this case dumper.exe) to
connect.  The routine that is used to pause is frameless.  The stack is
still available for inspection via something like 'x/100x $esp' but the
stack trace is often munged in this scenario.
