Started with r216750.
Note that we ICE even on
template<int sz> void make_item()
{
static int i{100};
struct
{
int id{i++};
} item;
}
int main()
{
make_item<0>();
}
which is accepted by 4.9 and clang.

So it seems current_class_ptr is no longer just NULL or a PARM_DECL, but can be
also ADDR_EXPR of a PLACEHOLDER_EXPR. Dunno if the right fix is
just
bool
parsing_nsdmi (void)
{
/* We recognize NSDMI context by the context-less 'this' pointer set up
by the function above. */
- if (current_class_ptr && DECL_CONTEXT (current_class_ptr) == NULL_TREE)
+ if (current_class_ptr
+ && TREE_CODE (current_class_ptr) == PARM_DECL
+ && DECL_CONTEXT (current_class_ptr) == NULL_TREE)
return true;
return false;
}
or something different.

Hmm, this issue seems to be fixed by delayed folding. By it I get the
following error-message:
t3.cpp: In function 'int main()':
t3.cpp:13:16: error: expected primary-expression before ')' token
make_item<0>();
^
So there is still a parser-error, if this piece of code is considered to be
valid code

This change is OK.
