Linking problem between 2 projects

[RafaelNMeyer]

Hi, we are issuing an issue between 2 projects.
The first has the POCO library statically linked and the second dynamically.
The main problem is that when the first project calls the second one, the POCO functions don't work correctly.
But when we disable some build options with conan options in the first project, the projects work normally again.

We discovered (or imagined) that the problem is between the 2 projects. The first links to pthreads and has weak symbols and the second also links to pthreads, but when calling a libstd++ function, it causes a segmentation fault. We are still looking for a way to resolve this!
