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?
