Indeed ... *please* tell us your compiler issued a warning about that.
If not an error --- none of the compilers I use will take it at all.
Maybe you need to get a real C compiler.

Well, you oughta allocate result before you store into it, not after,
and I bet you meant to assign to the tvi and tvf fields, not tvi twice.

Bad as these mistakes are, they don't directly explain why a later index
entry creation would fail.  What I'm betting is that your CREATE TYPE
command does not correctly describe the datatype size.  Based on this
code it should be pass-by-reference, fixed-size-8-bytes, but I'll bet
a nickel your CREATE TYPE says something else --- probably varlena.
