Description thomas.bockman 2016-05-18 02:17:32 UTC 
This works fine without optimizations, or with optimizations on GDC and LDC.

Both 32- and 64-bit are effected.

module app;

F foo(F)(F x)
{
    F ret = 1;
    ret = -ret;
    return ret;
}

void main() {
    import std.stdio;
    writeln(foo(-168.1234L));  // DMD: -1
    writeln(foo(-168.1234));   // DMD:  1
    writeln(foo(-168.1234f));  // DMD:  1.00002
