PyList_New is nil about nimpy

[andreaferretti]

I have tried adding this snippet in the body of nimArrToPy:

echo pyLib.Py_BuildValue.isNil
echo pyLib.PyTuple_New.isNil
echo pyLib.PyTuple_Size.isNil
echo pyLib.PyTuple_GetItem.isNil
echo pyLib.PyTuple_SetItem.isNil
echo pyLib.Py_None.isNil
echo pyLib.PyType_Ready.isNil
echo pyLib.PyType_GenericNew.isNil
echo pyLib.PyModule_AddObject.isNil
echo pyLib.PyList_New.isNil
echo pyLib.PyList_Size.isNil
echo pyLib.PyList_GetItem.isNil
echo pyLib.PyList_SetItem.isNil

and I get

false
true
true
true
true
true
true
true
true
true
true
true
true

so apparently Py_BuildValue is the only symbol loaded (among the ones I tested)

Looks like memory corruption of some sort. load template would raise exception in case of error. If you don't mind debugging, I'd try break soon after the syms are loaded, and set watchpoint for them (e.g. on pyLib.PyTuple_New).

[andreaferretti]

I confirm that after loading, the symbols are indeed not nil. But later, they all become nil.

I don't mind debugging, but unfortunately I am not familiar with how to work with a debugger... :-(

Ping me on gitter pls

Fixed, but depends on nim-lang/Nim#7885

Great, thank you! Nimpy is really improving fast!
