I have more information.While doing some more experiment, I noticed that at some point a floating-point exception was thrown.
In the documentation, it says that floating-point exception are disabled by default. It further says that have floating-point exception enabled would disable the setting of ieeeFlags. I was also unable to disable those exception manually.
Still hoping someone telling me how stupid I am and that is not a D bug (omg this language has some puns potential...)
