default:
- if (typeSizes[type] == -1)
- return -1;
- length = typeSizes[(type & 0xf)] * count;
- if (length < 0 || (se && (s + length) > se))
+ /* this won’t overflow, since ‘long_count’ is 64-bit */
+ length = typeSizes[type] * long_count;
+ if (length <= 0 || (se && length > se - s))
I went with making `typeSizes` 64-bit, which will help prevent similar problems
elsewhere.
