New submission from Matteo Cafasso:
The following code snippet:
----------------------------------------------
#include <stdio.h>
#include <Python.h>
int main()
{
char *broken_string[8];
char broken_char = 4294967252;
sprintf(broken_string, "%c", broken_char);
PyUnicode_FromString(broken_string);
}
----------------------------------------------
Produces a Segmentation Fault.
Is this behaviour the expected one?
The real life example comes when reading a malformed path on a Ext4 filesystem.
The read string causes PyUnicode_FromString to segfault.
