Subject: IMPORTANT: Static objects are evil.
X-MARC-Message: https://marc.info/?l=kde-devel&m=96225816819316

Hiya,

Short version:
==========
Static objects are evil. Do not use them. If you really need a static object, 
use a static pointer instead. E.g. like this:

{
   ...
   static MyObject *my_static_pointer = 0;
   if (!my_static_pointer)
      my_static_pointer = new MyObject();
   ...
}


Long version:
==========

Static objects in DSOs (shared libraries) are not very well supported and 
currently cause segmentation faults on exit, after returning from main(), if 
the DSO containing the static object was unloaded (with dlclose) by the 
program.

Cheers,
Waldo
