And I can get past R CMD check Rcpp if I include -O3 in CXXFLAGS.

Interesting. Stabilizing a compile by using the optimization flags. The runs I
reported
earlier (with Apple's g++-4.2, Apple's llvm g++-4.2, and g++-4.7 from svn)
all used the -O4 flag. Although the symptoms are the same as mine, it seems
the disease is different.

OK, this is bizarre. I am able to install the RcppArmadillo package
on my current setup provided that I turn on optimization in the call
to g++ to compile RcppArmadillo.cpp. The only difference between the
following two calls is the -O3 flag. (I haven't tried other levels of
optimization yet but
Yes, well, this still does not explain why Doug gets the same error
on Ubuntu.

Yesterday I upgraded to Ubuntu 11.04 for which the default g++ version is 4.5.2
I rebuilt R-devel and R-patched from the sources and things changed --
R-devel CMD check Rcpp now fails at a different point. This time it
doesn't segfault but it does produce results that are different from
the refer

I suggest filing a bug with Apple. The

(Conrad, This started as this thread
http://thread.gmane.org/gmane.comp.lang.r.rcpp/1877
which picks up the issue first reported by Jan regaring arma_version not
being found by the linker and which you commented on so colourfully a few
days ago.)
