This is one case where we can have either DECLs or TREE_LISTs

different testcase

This one has declaration of overloaded functions in function scope. The assert
is the same.

------- Comment #6 from jakub at gcc dot gnu dot org  2010-08-18 12:32 -------
This is broken for more than month, by a change which didn't fix any bug, nor
improved code generation nor compilation time; I'd say DECL_CHAIN should drop
the DECL_MINIMAL_CHECK test unless this is resolved soon, either by reverting
those places to use TREE_CHAIN again instead of DECL_CHAIN, or use
if (DECL_P (x)) ... DECL_CHAIN (x) ... else ... TREE_CHAIN (x) ...;
