But the above just fixes the symptoms, it's probably not the correct
way to test for a nested function.


DECL_NO_STATIC_CHAIN (decl) should be true for this function but
why is it not?


/* In a FUNCTION_DECL with a nonzero DECL_CONTEXT, indicates that a
   static chain is not needed.  */
#define DECL_NO_STATIC_CHAIN(NODE) \

It looks like the -fwhole-program version of ClearLeft only passes the
first 2 arguments to the ClearInLine call in register, the 3rd one is
passed on the stack.
The reason for that is this code in i386.c:ix86_function_regparm:


Maybe a better check would be check in the decl's function struct's 
field

static_chain_decl is set.
