&
trim(path) // "forty two" /) )
contains
subroutine print_strings (s)
character(*), intent(in) :: s(:)
integer :: i
do, i=1, size(s)
print *, i, '>', s(i), '<'
end do
end subroutine
end program

Slightly different test case - using allocatable string length instead of the
trims. However the same problems are evident:
program testch
implicit none
character(:), allocatable :: path
path = 'xyz

Third variant. This one messes up NAG and PGI too:
wws@w6ws-4:/tmp$ cat testch3.f90
program testch
implicit none
character(:), allocatable :: path(:)
path = 'xyz/'
path = (/ character(16) :: &

Here's another snippet. gcc-8.0.0-alpha20180422 snapshot (r259553) w/ r259563
applied ICEs when compiling it for x86_64 w/ -O2 (-O3, -Os)
-ftree-slp-vectorize -fschedule-insns -fsel-sched-pipelining
-fselect
