Program crash for array copy with ifort

Question

This program crashes with Illegal instruction: 4 on MacOSX Lion and ifort (IFORT) 12.1.0 20111011

program foo
      real, pointer :: a(:,:), b(:         


        

Answer 1

Use "allocatable" instead of "pointer".

real, allocatable :: a(:,:), b(:,:)

Assigning a floating point number to a pointer looks dubious to me.
