problem with temporary arrays

With ifort 19.x I get a segfault when I pass a temporary array of a certain length to an internal procedure. This works fine with gfortran and pgf90.  Is this a bug in the compiler?

You are most likely running out of stack. Try compiling with -heap-arrays. .

You SEGFAULT here:

real     ( 8), dimension(n) :: at,bt

or here:

at-bt

Not in the subroutine.

And it is stack overflow just as Steve have pointed out.
