This invalid variant is accepted, but segfaults at runtime :

program p
integer, parameter :: a(2) = [1, 2]
print *, reshape([3], a)
end
$ gfortran-12-20211114 z2.f90 && ./a.out
Program received signal SIGSEGV: Segmentation fault - invalid memory reference.

$ gfortran-12-20211114 z2.f90 -g -O0 -fcheck=all && ./a.out
Fortran runtime error: Incorrect size in SOURCE argument to RESHAPE intrinsic:
