Please submit a full bug report,
with preprocessed source if appropriate.
Please include the complete backtrace with any bug report.
See <http://gcc.gnu.org/bugs.html> for instructions.
No special compiler flags required.
This code used to compile with trunk dated 2012 Oct 03, so
a recent change seems to be causing the problem.
