pointers to objects in shared library (Linux)

[Zorro]

Is there something in particular I must know about Linux Shared libs?
Any help will be appreciated. Here is the question.

I am passing a pointer, to a pointer, to an object that will be
created in a shared library. This is as simple as I am saying it, and
it works fine with a dll. However, in Linux, as soon as the call
returns the pointer to the object in the library seems to be pointing
to junk, and I get seg-fault. The object is not destroyed to be sure,
in fact it is created via new, and not deleted at that time.

Thank you.

Actually, I must thank you for asking. It has been three days of
frustration to find where the problem was, and at least a whole day of
so why is this happening (after locating the problem).

I noticed that template structures where not identical, something was
changed (in near million lines) on Windows, but not on Linux. So, the
structure pointed to in the library, was not identical to structure
pointed to in the loader of the library.

I appreciate quick response. Have a great day Venu.
