string.val isn't a C string (notice the "not null terminated" comment in
the structure definition), and you can't call numeric_out like that.
Either of those would crash it.

You could use pnstrdup to get a valid C string, and use
DatumGetCString(DirectFunctionCall1(
                  numeric_out,
                  NumericGetDatum(ptr->value.val.numeric)))

to get the numeric value as a C string.
