As described in 
http://code.google.com/p/address-sanitizer/wiki/AddressSanitizer#Getting ,
I checked out the sources and they compile my simple helloworld-style app fine 
with -O1/-O2:

$ ~/asan/asan_clang_Linux/bin/clang -O2 -fasan -g -m32 simple_oob.cpp -o 
simple_oob_asan
$ ~/asan/asan_clang_Linux/bin/clang -O1 -fasan -g -m32 simple_oob.cpp -o 
simple_oob_asan
$ ~/asan/asan_clang_Linux/bin/clang -O0 -fasan -g -m32 simple_oob.cpp -o 
simple_oob_asan

This initially was a feature. Not sure we still need it.
