64-bit fedora 14. For building R svn (and checking soon-to-be-released R 
packages, rather than daily R-related work), I also have these, and indeed have 
"--enable-strict-barrier":

export DEFS='-DUSE_TYPE_CHECKING_STRICT -DR_MEMORY_PROFILING' \
./configure --enable-memory-profiling --enable-strict-barrier 
--enable-byte-compiled-packages --with-valgrind-instrumentation=2

 > sessionInfo()
