Exception context lost while using dynamic exception-aware libraries

[jchapon]

Hello

I tried exceptions4c in an application with dynamic libraries like this:

program
 |_ lib1.so          (uses exception framework)
      |_lib2.so      (uses exception framework)

In my case, the context is lost between lib1 and lib2 even if the macro e4c_reusing_context is used.

The first tests were OK but with static libraries only.

I tested test_h08, edited to simulate my case, and here are the results in a static and dynamic way : ** static **
