Hi, Simply by adding BOOST_CLASS_EXPORT(MyClass), all executables, unit tests, etc. which compile with this class failed at the end of the execution with a seg fault. All the process is done but the application exit with a seg fault. I encounter this problem with some classes and not with others... I don't understand where the error comes from and I don't arrived to reproduce on a simple test. Best regards, Fabien Castan Program received signal SIGSEGV, Segmentation fault. strcmp () at ../sysdeps/i386/i686/strcmp.S:40 40 ../sysdeps/i386/i686/strcmp.S: Aucun fichier ou dossier de ce type. in ../sysdeps/i386/i686/strcmp.S Current language: auto The current source language is "auto; currently asm".
