Fix two memory leaks in _XFreeX11XCBStructure()
|
|
|
|
Even when XCloseDisplay() was called, some memory was leaked.
|
|
|
|
XCloseDisplay() calls _XFreeDisplayStructure(), which calls
|
|
_XFreeX11XCBStructure().
|
|
|
|
However, _XFreeX11XCBStructure() did not destroy the condition variables,
|
|
resulting in the leaking of some 40 bytes.
