Message-ID: <E1h4hkt-0006Nu-HX@gemulon.postgresql.org> (raw)
Fix volatile vs. pointer confusion
Variables used after a longjmp() need to be declared volatile. In
case of a pointer, it's the pointer itself that needs to be declared
volatile, not the pointed-to value. So we need
PyObject *volatile items;
instead of
volatile PyObject *items; /* wrong */
