[Rd] Problem with compiling - Freebsd on AMD64 (PR#7489)

[Prof Brian Ripley]

In what sense is this a bug in R?  If changing your compiler optimization 
leads to a segfault, it looks very like a compiler bug.  So what was the 
compiler?

[R does work using AMD64 on Linux, but only correctly with gcc >= 3.3.3.]

BTW gdb output with "-g -O2" (the R default) ought to be informative, so 
was this with -O?
