I'll have a look...
Reduced test case much appreciated (you know about the "delta" tool?).

Works for me at trunk r185035, configure options:
../trunk/configure --with-mpfr=/opt/cfarm/mpfr-2.3.1
--with-gmp=/opt/cfarm/gmp-4.2.4 --with-mpc=/opt/cfarm/mpc-0.8
--enable-languages=c --disable-libmudflap --disable-libssp --disable-libitm
--disable-lto --target=arm-linux-androideabi

Can you please show your configuration and the trunk revision you are using?

Created attachment 26851
  --> http://gcc.gnu.org/bugzilla/attachment.cgi?id=26851
slightly reduced test case

I'm familiar with delta, but it's not very useful in this particular case.
The attached file is the result of running multidelta and doing some manual
work (e.g. eliminating useless typedefs).
