Summary: T_ULONG -> double rounding in PyMember_GetOne()
Initial Comment:
Problem:
Python/structmember.c's PyMember_GetOne currently
handles getting T_ULONG members as follows:
case T_ULONG:
v = PyLong_FromDouble((double) *(unsigned
long*)addr);
break;
On platforms with 64-bit longs, the double won't have
enough precision to hold big values without rounding.
The fix should be simple:
v = PyLong_FromUnsignedLong(*(unsigned long*)addr);
