            Bug ID: 23896
           Summary: (Windows) LLDB hangs if debuggee raises an exception
                    during startup
           Product: lldb
           Version: unspecified
          Hardware: PC
                OS: Windows NT
            Status: NEW
          Severity: normal
          Priority: P
         Component: All Bugs

    Classification: Unclassified

Start debugging executable that depends on some dll, but make sure that the dll
cannot be found.  This will cause SEH exception 0xc0000135 to be raised by the
image loader.  LLDB's debug loop thread receives the debug event, notifies the
main thread and waits...  Meanwhile the main thread is blocked (in
ProcessWindows::WaitForDebuggerConnection) waiting for debug launch to
complete. Whoops.

LLDB version: tip of the master as of 6/18/15
