Modules/_io/bufferedio.c:_bufferedreader_read_all() doesn't call Py_XDECREF(data) multiple times and may leak a reference in an error case. For example the ref leak occurs when current_size > 0 and PyObject_CallMethodObjArgs(self->raw, _PyIO_str_readall, NULL) fails orbuffered_flush_and_rewind_unlocked(self) fails. There are a few more places where data isn't decrefed on return, too. CID 715364 (#2 of 2): Resource leak (RESOURCE_LEAK) leaked_storage: Variable "data" going out of scope leaks the storage it points to. |
