<pre>For this sample code:
#include <cstdarg>
#include <cstdio>
int main()
{
auto test = [&](const char* fmt, ...)
{
va_list ap;
va_start(ap,fmt);
char Buf[1024];
std::vsprintf(Buf, fmt, ap);
va_end(ap);
std::puts(Buf);
};
test("Test %d", 1);
}
Clang++-3.6 incorrectly gives the following error message:
tmp.cc:9:9: error: 'va_start' used in function with fixed args
va_start(ap,fmt);</pre>
