Compilation of <vector> and self-defined 'distance(a,b)' fails

[Benjamin King]

Hi GCC team,

I think my gcc has a bug. It fails to compile the following program. Renaming 'distance' to anything else solves this, so I guess that the 'distance' function from <iterator> somehow escaped the std::-namespace.
I couldn't find any description about this with google or in the gcc bug database.

cheers,
   Benjamin


My code (see attachment for .ii):
---
#include <vector>

double distance(const std::vector<double> & v1, const std::vector<double> & v2) {
   return 0;
}

int main(int argc, char* argv[])
{
   std::vector<double> v;
   double d;
   d = distance(v, v);
   return 0;
}
