[Bug c++/30763] New: problem with bit-fields assignment

[vovanec at gmail dot com]

Test case:
#include 

#define INT_INVALID -1

class Test
{
  int b : 16;
  int a;
  int c : 16;

public:
  Test()
  {
b = a = c = INT_INVALID;
//a = b = c = INT_INVALID;
  }

  void dump()const
  {
printf("a: %d\tb: %d\tc: %d\n",a,b,c);
  }
};

int main()
{
Test a;
a.dump();
return 0;
}

g++-4.1 main.cpp
./a.out
a: 65535b: -1   c: -1

g++-4.0 main.cpp
a: -1   b: -1   c: -1

It seems like regression in GCC-4.1.1 and 4.1.2(on GCC-4.1.0 and earlier 
I've got correct results)

When order of assignment has changed (a = b = c = INT_INVALID;) 
test case returns correct values.
