SS9 CC5.6 compiler bug - algorithm count confused with struct member

Question

Found some code that fails to compile in CC 5.6
CC: Sun C++ 5.6 2004/07/15
#include <algorithm>
using namespace std;
struct A {
  int count;   
struct B
  struct A *a;
int main(int argc, char **argv)
  struct B *b = 0;
  // This line fails to build, any other operator is ok
  if ( b->a->count < 50 )
  return (1);
}Fails with error :
"c56_algorithm_bug.cpp", line 21: Error: Unexpected ")" -- Check for matching parenthesis.
"c56_algorithm_bug.cpp", line 22: Error: "," expected instead of "{".
"c56_algorithm_bug.cpp", line 22: Error: Illegal value for template parameter.
"c56_algorithm_bug.cpp", line 22: Error: ")" expected instead of "{".
4 Error(s) detected.The compiler is getting confused with the use of the count struct member vs the count algorithm. Changing the < to a > fixes the problem.
Using CC5.3 works fine as well as all other compilers we use (gcc 3.4, mipspro 7.4, VC 7.1)
Anyone seen this ?

This bug has been fixed in the C++ 5.6 compiler. I'm not sure if the fix is in the first patch which is about to be released. If not, the fix definitely will be in the next patch.
The workaround is not to use
using namespace std;That using-declaration is a pretty big hammer, and often results in conflicts with user code, compiler bugs aside.
