--- Comment #2 from Dominique d'Humieres <dominiq at lps dot ens.fr> ---
With --enable-checking=yes I get

pr98890.f90:3:19:

    3 |   real function bar(x)
      |                   ^
Error: type mismatch in binary expression
real(kind=4)

real(kind=4)

real(kind=4) (*<T5e4>) (real(kind=4)[4] * restrict)

_2 = _1 * baz;
pr98890.f90:3:19: internal compiler error: 'verify_gimple' failed

With --enable-checking=release and GCC8 to 11, I get

    5 |     bar=baz*x(1,1)
      |                  ^
internal compiler error: in convert_mode_scalar, at expr.c:314

For GCC7 I get

internal compiler error: in convert_move, at expr.c:229
