[Patch, Fortran] PR 50070: Segmentation fault at size_binop_loc in fold-const.c

[Janus Weil]

Hi all,

here is a small patch for an ICE-on-invalid problem with COMMON and
character length. I was kinda surprised that we don't catch this
already. The fix is rather simple, but after the amount of discussion
(that I had with myself) in the PR, I probably cannot claim that it
was 'obvious' to me.

In any case, the patch was regtested on x86_64-unknown-linux-gnu. Ok for trunk?

Cheers,
Janus
