Sorry for the delay in replying. It was busy here with the R/Finance
conference I helped put together.

Interesting.  I tend to have -O3 set in CXXFLAGS and CFLAGS in ~/.R/Makevars
so it gets used. 

I lean towards filing this under compiler bug. The template stuff may be
pushing the compiler a little. Does removing -g make a difference?

So is that a good enough modus operandi for you?
