I ran into some odd behavior when working on my cython-based project
(h5py). The following cython code snippet is the culprit ("priv" is a
function argument of type void**):
cdef conv_size_t *sizes
priv[0] = sizes =<conv_size_t*>malloc(sizeof(conv_size_t))
gets turned into this (with Cython 0.14.1):
(__pyx_v_priv[0]) = ((__pyx_t_4h5py_5_conv_conv_size_t
*)malloc((sizeof(__pyx_t_4h5py_5_conv_conv_size_t))));
__pyx_v_sizes = ((__pyx_t_4h5py_5_conv_conv_size_t
*)malloc((sizeof(__pyx_t_4h5py_5_conv_conv_size_t))));
This is fixed in the latest master branch.
Ah, sorry. It was actually broken, even though my test run initially told
me otherwise. Strange ...
The problem was the C type cast, which was incorrectly considered a
"simple" expression that didn't need a temporary assignment. Malloc is the
most obvious case where this hits, as it's almost always used through a cast.
It's fixed now. Thanks for report and example.
