[Numpy-discussion] More intel about the bug "Reference count error detected"
Tue Oct 30 03:46:45 CDT 2007
I'm trying to debug what is going on, but I do not know much about the
universal functions. I'm trying to understand what PyUFunc_GenericFunction()
does and what the parameters should be.
Perhaps I should move to the numpy development list ?
