PR c/89933
* c-decl.c (merge_decls): When newdecl's type is its main variant,
don't try to remove it from the variant list, but instead assert
it has no variants.

* decl.c (duplicate_decls): When newdecl's type is its main variant,
don't try to remove it from the variant list, but instead assert
it has no variants.

* c-c++-common/pr89933.c: New test.
