[Bug c++/15142] New: Internal compiler error when passing a string where a char* is expecteted in a throw statement

[micis at gmx dot de]

when compiling this small (and silly) program I get an internal compiler error:
bug34.cpp: In function `void SillyFunc()':
bug34.cpp:12: warning: cannot pass objects of non-POD type `struct std::string' 
through `...'; call will abort at runtime
bug34.cpp:12: internal compiler error: in cp_expr_size, at cp/cp-lang.c:347
Please submit a full bug report,

#include <string>
class Err
{
    public: Err(char *aErrText,...) {}
};

void SillyFunc()
{
    std::string fullname;
    throw Err("failed %s",fullname);
}

Here we go: 
----------------- 
struct B { 
    B() throw() { } 
    B(const B&) throw() { } 
}; 
 
struct X { 
    B a; 
    X& operator=(const X&); 
}; 
 
struct S { S(...); }; 
 
void SillyFunc() { 
  throw S(X()); 
}

This looks similar to bug 11971 which was fixed for 3.4.0.
