R devel - Sep 2014 - possible error in rdevel with --enable-strict-barrier?

Hi,

With a fresh Rdevel r66690 (yesterday 26th) in ~/R/Rtrunk I get :

~/R/Rtrunk $ ./configure CC="gcc -std=gnu99 -fsanitize=address" 
CFLAGS="-fno-omit-frame-pointer -O0 -g -Wall -pedantic -mtune=native" 
--without-recommended-packages
~/R/Rtrunk $ make clean
~/R/Rtrunk $ make

Works fine.

Now adding --enable-strict-barrier to the end :

~/R/Rtrunk $ ./configure CC="gcc -std=gnu99 -fsanitize=address" 
CFLAGS="-fno-omit-frame-pointer -O0 -g -Wall -pedantic -mtune=native" 
--without-recommended-packages --enable-strict-barrier
~/R/Rtrunk $ make clean
~/R/Rtrunk $ make
... snip ...

I've done this with and without --enable-strict-barrier several times 
and it's repeatable, at least on my machine.

Am I doing it right?  Is it known?

gcc version 4.8.2 (Debian 4.8.2-1)

I should mention that I've also installed gcc 4.9.1 to try combining 
ASAN and UBSAN i.e. -fsanitize=undefined,address.  So it's possible that 
something in that install has upgraded a shared object somewhere else.  
In the command above I'm using just "gcc" in CC, though, not
"gcc-4.9".
The earlier snipped output confirms it is using gcc 4.8.2.

Anyway, posting here to see if it's just me or if there's really a minor
issue with Rdevel currently.

Thanks,
Matt
