--- Comment #1 from Georg-Johann Lay <gjl at gcc dot gnu.org> 2012-04-22 23:35:49 UTC ---
Confirmed with mingw32 canadian cross for 4.7.0 and 4.7.1 (prerelease) from
2012-03-22.

The following line triggers the ICE:

$ avr-g++ -mmcu=atmega328p -gdwarf-2 -Os -c ahrs.cpp

whereas removing -gdwarf-2 works fine.

Is this a duplicate of PR52662?
