[New-bugs-announce] [issue25659] ctypes.Array.from_buffer segmentation fault when trying to create from array.array

[Ely Spears]

New submission from Ely Spears:

I'm trying to find a way to create a ctypes array from the underlying memory buffer exposed by an array.array object. The ctypes.Array.from_buffer function isn't documented, but I did find the source code in _ctypes.c around line 497. It's not clear to me where the problem might be.


Code to reproduce it below:

import array, ctypes
a1 = array.array('l')
a1.fromlist(range(10))
ctypes.Array.from_buffer(a1)
#Segfault
