The following code leads to an internal compiler error with Intel(R) Visual Fortran Compiler 19.1.3.311 [Intel(R) 64]

program test
	implicit none
	integer, parameter :: n=10
	real	:: x(n)
	integer :: inds(n),i
	
	inds=[(i,i=1,10)]
	x=0
	x(inds(nint(.15*n):))=x(inds(nint(.15*n):))+1
end program test

The ICE also occurs with 2021.3.0 on Windows (ifort as well as ifx). Here is a work around:

i = nint(.15*n)
x(inds(i:))=x(inds(i:))+1

@Ulrich_M_  Thanks for reporting this ICE.

@mecej4  Thanks for the workaround!

I filed a bug report, CMPLRIL0-34036, against both ifort and ifx. I'll let you know its progress to a fix.

I just checked this issue with the latest ifort release 2021.6.0. The ICE you reported is gone.

This version of ifort is part of oneAPI 2022.2 that was recently released.
