Synopsis: constructor executed at least twice

State-Changed-When: Tue Apr  9 09:40:13 2002
State-Changed-Why:
    Your bug report doesn't mention actual bad code semantics; the gdb behavior you mention is common for optimized code.  It may not be ideal, but it's not a bug either.

>Description:
	when running gdb (GNU gdb 19990928) on the generated code, the
declaration of f is executed twice.  moreover, weird stepping into the
string construnctors occurs.  after that, the program is probably
non-deterministic.

>How-To-Repeat:
compile with -O -g
note that with the .ii file, only the strange stepping into the string
constructor occurs (if using the next command of gdb). 

i include bug.cc and bug.ii


// compile with -g -O
#include <string>

struct foo { std::string s ; } ;

int main() { foo f ; }


>Fix:
don't optimise
