In fact, TSomeForm.Create(Application) should work and should be enough 
for all cases. In my vision, the purpose of Application.CreateForm is a 
workaround for odd VCL architecture: it assigns object reference before 
calling its constructor, so that you can use global variables like 
"Form1" within FormCreate handler without getting a segfault. But doing 
so is bad, extremely bad practice...

Finding a solution of the problem is always better, although harder, 
than masking it out :)
