[gdb/python] Fix cpychecker error in recpy_bt_goto
Commit Message
Hi,
When using cpychecker, we run into this error:
...
gdb/python/py-record-btrace.c: \
In function ‘PyObject* recpy_bt_goto(PyObject*, PyObject*)’:
gdb/python/py-record-btrace.c:783:25: error: Mismatching type in call to \
PyArg_ParseTuple with format code "O" [-Werror]
if (!PyArg_ParseTuple (args, "O", &obj))
argument 3 ("&obj") had type
"const struct recpy_element_object * *"
but was expecting
"struct PyObject * *"
for format code "O"
...
Fix this by using a new variable of the expected type instead.
Build and reg-tested on x86_64-linux.
OK for trunk?
Thanks,
- Tom

There should be a space after the close paren.
Ok with that change.
