SQLITE_TEST is not set.

Further experimentation, by setting a breakpoint on
sqlite3_create_function(), shows that this does not seem to be called
as the breakpoint is not triggered.  I am not sure what is going  
on here

It doesn't make a lot of sense.

I agree, but in what way do you mean it does not make sense?

How exactly did you build sqlite3?

Using the freebsd ports system.  I edited the Makefile to force  
debugging on and add a CFLAGS with --g -O0 in that case.

Have you tried 3.5.1?


No.  I've been using what is in the FreeBSD ports system (my last  
update of the ports was about 1 month ago).
