--- Comment #1 from Mikael Pettersson <mikpe at it dot uu.se> --- With -m64: both test cases work with gcc-3.2.3, and fail with every release from 3.3.6 up to current trunk. With -m32: the first test case doesn't trap with any release since 3.2.3, the second test case traps with current trunk and 4.8, but not with any release from 3.2.3 to 4.7.3.
