C++ UDF produces fatal crash with carriage return chars about duckdb

[prmelehan]

I noticed this might be a function of string inlining, where a new pointer is created for non inlined strings?

Also, I noticed that the test suite does not take into account functions that modify string values and return new ones:

duckdb/test/api/udf_function/udf_functions_to_test.hpp

Lines 117 to 125 in 10ea483

	inline string_t udf_varchar(string_t a) {
	return a;
	}
	inline string_t udf_varchar(string_t a, string_t b) {
	return b;
	}
	inline string_t udf_varchar(string_t a, string_t b, string_t c) {
	return c;
	}

Only returning the original value...

Am I incorrect here?

This is blocking critical development for us, so any help would be much appreciated !
