I have a project which includes barswf_cpu - in this one there is no POCO_STATIC; 
in Preprocessor Definitions
in two other subprojects barswf_brook and barswf_cuda there is POCO_STATIC; 
in Preprocessor Definitions:
in those subprojects when it tries to execute:
    g->log->information("------------------------------");
    g->log->information("BarsWF started");

it crushes when tries to allocate memory!

According to:
https://pocoproject.org/docs/99150-WindowsPlatformNotes.html

- The default is to link the POCO C++ Libraries dynamically (DLL).
- To link statically, the code using the POCO C++ Libraries must be compiled with the preprocessor symbol POCO_STATIC defined.

The question is: will the dynamically linking (dlls) slow down the bruteforce process: the speed of executing program?

I am still confused regarding Poco dll name convention:

Hi. Some good news: I've used include files directory (.h files) from an very old Poco and I've used libs from a newer Poco
I've set POCO_STATIC in Preprocessor Definitions of all projects;
now this thing works fine on all builds!
