[Patch, Fortran] PR fotran/35820 again: memory leak while resolving nested foralls.

[Dominique Dhumieres]

> For Dominique, one can add this to make a memory leak results in an ICE:

The three codes associated to this pr give an ICE with the patchlet
without any other patch. All the ICEs disappear with the first patch
(and also with the second one). Otherwise the second patch regtested
without regression and own tests worked as usual.

Thanks

Dominique
