jmestwa-coder opened a new issue, #50078:
URL: https://github.com/apache/arrow/issues/50078
### Describe the bug, including details regarding any error messages,
version, and platform.
`AppendTimestampBatch` in `cpp/src/arrow/adapters/orc/util.cc` converts ORC
second + nanosecond timestamps to Arrow int64 nanoseconds with a bare `seconds
* kOneSecondNanos + nanos`. For a timestamp past ~year 2262 the multiply does
not fit in int64, which is signed integer overflow (UB).
Reducing the expression under `-fsanitize=signed-integer-overflow`:
```
runtime error: signed integer overflow:
10000000000 * 1000000000 cannot be represented in type 'int64_t'
```
The conversion should detect the out-of-range case and return an error
instead of computing the product with undefined behavior.
