Summary: ctypes leaks memory
Initial Comment:
This program leaks memory, because a string is allocated with the win32 call
SysAllocString(), but SysFreeString() is never called.
"""
from ctypes import oledll, _SimpleCData
class BSTR(_SimpleCData):
_type_ = "X"
func = oledll.oleaut32.SysStringLen
func.argtypes = (BSTR,)
while 1:
func("abcdefghijk")
"""
The attached patch fixes this.
(The BSTR data type is not exposed by ctypes or ctypes.wintypes, because it is
only used in connection with Windows COM objects.)
The patch should be applied to release25-maint and trunk.
