I think it is an internal thing with gcc that the size of a pointer and sizeof(int) are always the same, regardless of machine word size... with a 64-bit binary, sizeof(int) and sizeof(void *) should both be 8, which still causes them to be equal.

I see the same thing with PostgreSQL 8.0.0 (REL8_0_STABLE) on Solaris 9
and FreeBSD 4.11.
The intagg source code says
NOTE: This module requires sizeof(void *) to be the same as sizeof(int)
which in English means "this ain't gonna work on 64-bit machines". I've
never bothered to look at it more closely than that ...
Hmmm...the PostgreSQL binaries on my Solaris/sparc box are 32-bit and the FreeBSD box is a 32-bit i386, yet both are susceptible to the crash. On both boxes, a 32-bit program shows both sizeof(void *) and sizeof(int) to be 4, so the problem doesn't appear to be due to that necessary condition not being satisfied.
