Hi Fred,

Nope, not a bug. What you have here is a case of bad C++ code.
#1
int x, y; // This is good.
#2
int x; std::vector<double>::iterator y; // This is good.
#3
std::vector<double>::iterator x, y; // This is good.
#4
int x, std::vector<double>::iterator y; // This is not good.
You can't put #2 in a for-loop initialization expression (since it's two
expressions).
#1 and #3 won't do what you want.
#4 isn't C++, whether inside or outside of a for-loop initialization
expression..
HTH,
