A git bisect tracks the problem down to this commit.

[AArch64] Emit DATA_MAP in order within text section
2015-03-27 Renlin Li <renlin...@arm.com>
gas/
* config/tc-aarch64.c (mapping_state): Emit MAP_DATA within text
section in order.
(mapping_state_2): Don't emit MAP_DATA here.
(s_aarch64_inst): Align frag during state transition.
(md_assemble): Likewise.

The problem here is with the md_assemble change, which is calling
frag_align_code inside a loop, which means it can emit multiple
alignment frags with a single call. We are not in the text section,
which means we always get this alignment frag. These alignment frags
have variable size, and hence the .if test on dot no longer works.
This patch isn't present in the binutils-2.25 that tcwg is using. The
patch is present in binutils-2.26.
I've never looked at this MAP_DATA support, so the solution is not
immediately obvious to me.
Testcase attached.
