>Description:
Hello, the following simple code gives a parse error when compiling with g++, but works on both intel and solaris compilers. Is it a bug, or am I just missing something obvious? Thanks for any help.

> cat testVec.C
#include <stdio.h>

class A {
public:
  A() { printf("Acon\n"); }
  };

class B {
public:
  B(A a) { printf("BAcon\n"); }
  void form() { printf("Bform\n"); }
  };

int main() {
  B(A()).form();
}

> g++ testVec.C -o TestVec
testVec.C: In function `int main ()':
testVec.C:16: parse error before `.'

testVec.C

>How-To-Repeat:

>Fix:
use "A a; B(a).form();" instead of "B(A()).form();"
or add constructor A(int i) and use "B(A(1)).form();"
