real n = 6287.4;
float f() { return n; }

void main()
{
    assert(f() == f());
}

The assert fails, presumably because one value is on the stack, and another is in an FPU register.

Stumbled upon it while attempting:

allData.sort!((a, b) => a["!Price"].to!float() < b["!Price"].to!float())();

std.algorithm throws, because "Predicate for isSorted is not antisymmetric".

This is a dup of issue 8745.

You can use is operator for identity check.
