Yes. I agree that it is difficult. :-) I even thought about tracing
the stack from the bottom. ;-)
By the way, how to set priority of constructor?
I need constructor of my library (shared or static) to be called first,
so constructors of other libraries cannot call setenv() before I save
the value of *environ.
