    Using DBD::Mock, I've got a number of tests I'm using to validate my
    class that has-a DBI object. One set of tests verifies that I will
    return undef if handed the following SQL statements:

                SELECT 1 AS value FROM

                SELECT 1 AS value (with a bind param passed in)

                SELECT 1 AS value FROM foo WHERE x = ? (with no bind param
    passed in)

     

    On RH 9, perl 5.8.0 threading, DBI1.43, DBD::Mock 0.11 - this throws the
    following error (typed in, not cut'n'paste):

     

    Assertion I == (((((SV *) (name_av))->sv_flags & 0x00008000)) ?
    Perl_mg_size(((PerlInterpreter
    *)pthread_getspecific((*Perl_Gthr_key_ptr(((void *)0)))))), (SV *)
    name_av) : ((XPVAV*) *name_av)->sv_any)->xav_fill)+1 failed: file
    "DBI.xs", line 1638 at /usr/lib/perl5/site_perl/5.8.0/DBD/Mock.pm line
    372

     

    On Solaris 2.9, Perl 5.8.0 non-threading, DBI 1.43, DBD::Mock 0.11 - no
    error is thrown.

     

    DBD::Mock is an extremely basic DBD, which doesn't do any validation
    whatsoever of what's passed in. (The author and I have discussed adding
    this feature, but I am not taking advantage of it.)

     

    Is this a threading/non-threading thing or a Solaris/Redhat thing or a
    I'm-being-stupid thing? I don't have any other Perl's built. I could,
    but it would be a while before I found the time at work to build
    different Perls. (It's on the list for next month ... I hope.)

     

    Thanks,

    Rob Kinyon
