The problem here is that we are producing a REALPART_EXPR/IMAGPART_EXPR with the complex type instead of the sub type. See PR 22368 for the patch which is used to catch this. This shows up in the boostrap with that patch while building libgfortran.
Thanks, Andrew Pinski
ChangeLog: * tree-complex.c (expand_complex_libcall): Produce REALPART_EXPR/IMAGPART_EXPR with the correct type.
