Control: reassign -1 src:dragonegg 3.3-2
Control: retitle -1 dragonegg: ICE on simple program with gcc-4.7 4.7.3-13 and gcc-4.8 4.8.2-21

Same problem with 4.7:

Please submit a full bug report,
with preprocessed source if appropriate.
See <file:///usr/share/doc/gcc-4.7/README.Bugs> for instructions.
The bug is not reproducible, so it is likely a hardware or OS problem.

The problem with 4.7 disappears if I revert the gcc-4.7 packages
to version 4.7.3-12.
