Integer overflow, ifort internal compiler error

[zmi007]

I am just playing with integer overflow in fortran compilers and have found that this simple "buggy" fortran code causes internal compiler error by ifort on each of the write instruction. Gfortran detects these overflows and shows some "Error: Arithmetic overflow" during compilation.

program    integer_overflow
implicit none
    write(*,*) -(-2147483647-1)
    write(*,*) 2000000000 + 2000000000
    write(*,*) -2147483647 - 2147483647
    write(*,*) 46341 * 46341
    write(*,*) (-2147483647-1) / -1
end program integer_overflow

With ifort (IFORT) 15.0.2 20150121

ifort intel_bug.f90 -o intel_bug.x
intel_bug.f90: catastrophic error: **Internal compiler error: floating point exception signal raised**

Thanks - we'll check it out.

Escalated as issue DPD200369228. It's only the last of the expressions that triggers the error, though I would have expected the compiler to complain about the other expressions that overflow.

 I expect this to be fixed in update 1 of the 16.0 compiler.
