    K, so 1.11 is on CPAN which fixes this. However I have another bug
    report about this not working for user defined functions, where I do
    this:
    s = SvPV(result, len);
    sqlite3_result_text( context, s, len, SQLITE_TRANSIENT );
    (SvPV is a macro that retrieves a char* from result, and as a side
    effect sets len to the length of the string in bytes, even if it
    contains nuls).
    Is this maybe a bug in sqlite3_result_text()? I could patch it to do:
    if (memchr(s, 0, len)) {
    /* if the result contains NUL(s) treat it as a blob */
    sqlite3_result_blob(context, s, len, SQLITE_TRANSIENT );
    }
    else {
    sqlite3_result_text( context, s, len, SQLITE_TRANSIENT );
    }
    But that seems a waste of resources if it's a bug in
    sqlite3_result_text().
    I added a test case (check-in [2798]) that checks to make sure
    that sqlite3_result_text is able to deal with embedded '\000'
    characters in a string. I appears to work fine. I cannot
    reproduce the problem
    Can you suggest other ways of producing the problem?
