The usual priority is to use .so libraries if present and your objective is to produce a .so library, but the ACS Makefile has a small bug that resorts to .a libraries before the .so one.
This usually is inoffensive (although resulting in bigger binaries than required), however there are some cases that could result in double free of static symbols, which end up with a segmentation fault at exit.
An example is with the loggingClient:
free(): double free detected in tcache 2

A workaround is to compile with the MAKE_NOSTATIC environment variable set, however this should not be a requirement.
