everything that you allocated or reserved from FS must be given back and unreserved when you unload or it will create invalid pointers in memory.

Hello!

   I've made one module with one api function and one app function. I added one extension to call my app. I only print a console message whitin the app function. If I unload the module, make one change on the code, compile, install an reaload the module, when calling the extension which exec the app I get a core. I can see with gdb:

----------------------------------

----------------------------------

But I don't see which could be the problem. Any idea?
