File be/src/exprs/agg-fn-evaluator.cc:

PS6, Line 542:     Expr::InlineConstants(AnyValUtil::ColumnTypeToTypeDesc(intermediate_type()),
             :         AnyValUtil::ColumnTypesToTypeDescs(arg_types), codegen, *uda_fn);
> My comment wasn't advocating for the change of UDA interface but instead qu
It's not valid to call the UDF function directly with 'ctx', since it's not a FunctionContext
that was set up for that UDF.

The valid way to do that would be to have a helper function that was called by both CastToDecimalVal()
and some_date() with the correct types.

> Can you please keep it on a single line ?
Done
