 Hi,
 
 the PR can be reduced to the following code snippet:
 
 ----------------------snip here--------------------
 #include<string>
 
 struct C
 {
     C (std::string) {}
 };
 
 void foo ()
 {
     throw C(std::string());
 }
 ----------------------snip here--------------------
 
 This can be further reduced to:
 
 ----------------------snip here--------------------
 struct A
 {
     A ();
     A (const A&);
 };
 
 struct B
 {
     A a;
     B& operator= (const B&);
 };
 
 struct C
 {
     C (B) {}
 };
 
 void foo ()
 {
     throw C(B());
 }
 ----------------------snip here--------------------
 
 Compiling with "g++ -O -c" the main trunk (as of 20021007) crashes
 with the message (checked on i686-pc-linux-gnu and mips-sgi-irix6.5):
 
 bug.cc: In function `void foo()':
 bug.cc:15: internal compiler error: in cp_expr_size, at cp/cp-lang.c:304
 Please submit a full bug report, [etc.]
 
 The 3.2-branch and previous versions are not affected.
 
 Greetings,
 Volker Reichelt
