You haven't provided enough information for anyone to help you.

How are you compiling your function? Using pgxs, or some other way?

What's the full source code of the function?

Where does the server crash when it crashes? You might need to get a
backtrace of the server crash to help you figure out why your function
crashes it. See this documentation on getting a backtrace of a Pg
backend under windows:

If you are using a standard binary distribution of PostgreSQL then yes,
you should use Visual C++, preferably the same version of Visual C++
that was used for that version of PostgreSQL. Specify your version of Pg.
