State-Changed-Why:
Does the patch you provided in PR 3536 solve
this problem?
Hello,
The thunks were actually generated and found in the object files but they
were not public so linking failed. Adding the three lower lines to the
function make_thunk() in /gcc/cp/method.c seems solve problem 3536.
Line 361:
/* And neither is it a clone. */
DECL_CLONED_FUNCTION (thunk) = NULL_TREE;
DECL_EXTERNAL (thunk) = 1;
+ /* Make the thunk public unless it is for a destructor */
+ if (!DECL_DESTRUCTOR_P (func_decl))
+ TREE_PUBLIC (thunk) = 1;
