[C++][Gandiva] binary_string can throw an error if input is null #49034
Description
Describe the bug, including details regarding any error messages, version, and platform.
The binary_string function tries to allocate 0 bytes of memory if the input is empty. If this is the first row being processed there will be an error since no memory is allocated.
A fix is to either return early from the function before attempting to allocate memory or add kCanReturnErrors to indicate the errors aren't fatal.
