<pre>A user complained that a previous gcc cannot compile Chromium. The bug report
is:
<a href="https://gcc.gnu.org/bugzilla/show_bug.cgi?id=69753">https://gcc.gnu.org/bugzilla/show_bug.cgi?id=69753</a>
The reduced code is as follow:
class A {
public:
template <typename> void As();
static A *FromWebContents();
template <typename... Ts>
A *FromWebContents(Ts...);
};
template <typename T> class B : A {
void FromWebContents() {
auto guest = A::FromWebContents();
guest->As<T>();
}
};
After fixing the bug, the latest g++ accepts the code. I tried clang++, and it
rejects the code:
code3.cpp:11:9: error: use 'template' keyword to treat 'As' as a dependent
template name
guest->As<T>();
^
template
1 error generated.
Potentially, clang++ may fail to compile Chromium?</pre>
