Package: minc
Version: 1.4-4
minc produces a floating point exception on Alpha when I compile
it with a snapshot of GCC 4.2. I'm not entirely sure whether this is
a compiler bug or one in your package, but from other cases like these
it is likely that your package is doing something wrong and that newer
optimizations exhibit the problem.
Maybe you or your upstream can investigate. I'm also CCing Falk
Hueffner who knows about Alpha and GCC.
I've done some preliminary investigation which shows where the error
is:
in : short, out : double, norm : true, imgmax : true, valid : false
Program received signal SIGFPE, Arithmetic exception.
