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.
With 4.6 we did:
pr55570.c:1:1: error: requested alignment is not a constant
which was better than just segfaulting.
