[Interest] QMap<int64_t> significantly slower than QMap<int32_t>

Hi,

I'm experiencing this issue : a 64-bit int QMap slows my app comparing to a
32-bit int one. I'm compiling with GCC-MinGW64, so a 64-bit compiler.
Shouldn't it be as fast? The QMap is not very large (maybe 1000 elements)
and I have much bigger structures in my app, so the memory size should not
be responsible for the slowdown.

Thanks for help,

Etienne
