Well, an interaction between them. Certainly make check works on a lot of
systems with R 1.5.1.  It wouldn't get released otherwise.

No, that would be a really bad idea.

Looking at the forthcoming 1.6.0 I see that
   o   Workaround for optimization bugs on gcc 3.1/2 on 32-bit Solaris.
is listed in NEWS, so it might be worth either

a) reducing the optimisation level by editing CFLAGS in config.site
or
b) trying the pre1.6.0 code to see if the problem has gone away.
