Here is the same code in D:
void main(string[] args)

    import std.math;
    FloatingPointControl fpctrl;
    fpctrl.rounding = FloatingPointControl.roundUp;
    writefln("%.32g", float.min_normal + 1.0f);
}
Execution on my machine yields:
dmd -run test_denormal.d
1

Did I miss something?

This example is closer to the C++ one:

void main(string[] args)
{
    import core.stdc.fenv;
    fesetround(FE_UPWARD);
    writefln("%.32g", float.min_normal + 1.0f);
}

It still yields "1"
