Fixed NaN Assertion Error in Allocator for Function Bar

Why it matters

This fix addresses a rare crash scenario caused by an assertion failure in the allocator when handling NaN values as the last argument of the bar function. It improves stability and robustness by ensuring that a proper ClickHouse exception is thrown instead of an internal error, facilitating better error handling and diagnosis for users.

How to use it

Users do not need to enable anything explicitly. The fix is applied internally, and upon upgrading to this version, the system will handle NaN values passed as the last argument to bar with a standard exception instead of causing an assertion failure.
