Agreed.  Let me look some more.  Odd this succeeds:

    okapi           Gentoo 1.12.14 icc 11.1.072 x86_64

but this fails:

    mongoose     Gentoo 1.6.14 icc 9.0.032 i686

The backtrace:

    http://www.pgbuildfarm.org/cgi-bin/show_log.pl?nm=mongoose&dt=2011-09-01%2013%3A45%3A01

shows it failing on this line:

    size = offsetof(NDBOX, x[0]) +sizeof(double) * 2;

so I wonder if this is some compiler bug.  offsetof is:

    ((long) &((type *)0)->field)

and the struct is:

    typedef struct NDBOX
    {
        int32       vl_len_;        /* varlena header (do not touch directly!) */
        unsigned int dim;
        double      x[1];
    } NDBOX;

That "x" is quite a common symbol.  Is there any way to get access to
this machine?  Should I just revert it all and see what happens?
