Thanks Jason. I just see that the slightly revised example with an additional
defaulted c'tor gives me an ICE at the line marked with the X:
//-----------
template<class T,
class = decltype(T())
>
char f(int);
template<class>
char (&f(...))[2];
struct DelDtor {
DelDtor() = default;
~DelDtor() = delete;
};
static_assert(sizeof(f<DelDtor>(0)) != 1, "Error"); // X
int main() {}
//-----------
"main.cpp:14:34: internal compiler error: tree check: expected target_expr,
have
error_mark in build_cplus_new, at cp/tree.c:459"
I assume that should be reopened or shall I create a new entry?
The more detailed report via -v -save-temps gives the following output:
\Develop\cygwin\home\Daniel\jasongcc\bin\jasong++ -v -save-temps -std=c++0x
-Wall main.cpp
