Before the change, gfc_get_derived_type will search a module to reuse
TREE_TYPE.
The current one will create a new TREE_TYPE for the same type. But fold_convert
has
if (type == orig)
return arg;
Although TYPE and ORIG are the same type, they have different memory locations.
fold_convert doesn't handle it.
