Re: [Patch, fortran] PR31217 - ICE using FORALL on character substrings

Unfortunately not: If I regtest, I get an ICE (segmentation fault) for
the new forall_12.f90.

Minimal test case:
  character(len=1) :: b(4) = (/"1","2","3","4"/)
  forall(i=1:1) b(:)(i:i) = b(:)(i:i)

Valgrind shows (using Rev. 129442 and no other patches applied):

==14821== Invalid read of size 4

PS: Do you also plan to submit
It seems to fix all the problem reported in PR31608, which don't have
PRs of their own; that patch regtested successfully.
