* expr.c (component_initializer): Assign init expr to c->initializer.
(generate_isocbinding_initializer): New.
(gfc_generate_initializer): Call generate_isocbinding_initializer to
generate initializers for c_ptr and c_funptr with -finit-derived.

Sorry I have not tracked this issue down yet. My solution for -finit-derived requires special consideration for the iso-c-binding structures such as c_ptr since the structure intialization expression currently generated is invalid for those structures. Something in the middle-end changed with 8.x that has further invalidated my solution for -finit-derived. I am [still] working on this and a few other issues with -finit-derived.
