Passing by reference is a good habit to get into, but it doesn't buy you 
anything when the object being referenced is the same size as the 
resulting reference. (IE: passing anything larger than a pointer as a 
reference instead, saves the object from being copied to the stack).

Since your objects are (likely) the same size as a pointer, you're not 
getting anything out of passing by reference.

The only real question would be whether a const reference or a copy of 
the variable performs faster, but to discover that, you'd have to get a 
disassembly to see the overhead each way.

Syntactically, they are functionally equivalent. But if Solra is correct 
and your compiler is messing things up, you could just copy the function 
header, comment out one copy and change the other to pass all const 
references by value instead. A quick compile and test will tell you if 
that's where the problem lies. I suspect it's not the problem, but it 
would be quick to find out for sure.

Good Luck,
