Hi,
Now I found a reason for the crash in sqlite3_create_function() call.
SQLITE_CORE is not defined so icu.c [1] code expects I am using
sqlite3_api structure to redefining the API:

(in sqlite3ext.h:)
#define sqlite3_create_function        sqlite3_api->create_function

sqlite3_api is uninitialized, no reason it should be since I am not
using redefined API functions. I did as you recommended and compiled
the icu.c into my app without using extension. To avoid editing icu.c,
now I #defined SQLITE_CORE to 1 for this file and this helped.

I don't know if there is something to fix in the extension.
