Safe to define overloaded functions with array inputs in C++?

Is it safe to define the following two methods in C++ and use them without risk of them being mixed up in runtime?

void map(float (&a)[10], const double (&b)[6]);
void map(float (&a)[10], const double (&b)[3]);

or

void map(double (&a)[6], const float (&b)[10]);
void map(double (&a)[3], const float (&b)[10]);

They compile ok, so I figured their signature should be different and everything would be fine. However, I'm currently experiencing memory problems, so I want to make sure.

Yes, it is perfectly safe. Moreover, your sentence

without risk of them being mixed up in runtime?

makes absolutely no sense because overload resolution takes place compile-time.
