It builds fine on 2.20. This seems to work for me with the binutils version from sles10 (even with a vanilla build of binutils): $ as -v <<EOF; echo $? > .irp idx,0,1,2 > .if 0 > \idx > .endif > .endr > EOF GNU assembler version 2.16.91.0.5 (i586-suse-linux) using BFD version 2.16.91.0.5 20051219 0 $ So either the bug is fixed in that version already or you picked a wrong example (or I did not understand what should fail here). But don't get me wrong, I'm all for checking for actual bugs instead of innocent version strings.
