--- Comment #4 from airplanemath <airplanemath at aol dot com> ---
The line that the cygwin-native compiler crashes on:
attributes = gfc_add_attributes_to_decl (com->head->attr, NULL_TREE);
is not present in the Mingw-w64 cross compiler.  
Side-by-side debugging sessions reveal control flow 
through the two versions of build_common_decl are almost 
identical up to that point, except the cygwin-native 
compiler executes a line like
TREE_PUBLIC (decl) = 1;
which is not present in the Mingw-w64 execution.  
I asked for clarification on why the attributes line was 
there on the cygwin list.
