The cause is this code in 'FuncDeclaration::toObjFile':

if (multiobj && !isStaticDtorDeclaration() && !isStaticCtorDeclaration())
{   obj_append(this);
    return;
}

'multiobj' is true when -lib is passed, this unittest is then deferred to be
generated later (and it *is* generated later), however it never seems to be
run.

Anyway a qujick fix is to add a check for lib generation:

if (multiobj && !global.params.lib && !isStaticDtorDeclaration() &&
!isStaticCtorDeclaration()) { }

This makes the unittest work, but I don't know if that's a proper fix.

Any backend experts know more?
