[Discuss-gnuradio] Is the make check step essential?

Is the make check step essential.
I still got some errors with make check which are not yet resolved.
The following answer in another thead made me wondering is the make check step 
is essential:
> > Making check in tests
....

In other words.
Does make check set some settings for gnuradio or is it just informative.
If some of the factories are not working how does gnuradio know this.
I know gr_vmcircbuf_sysv_shm_factory is working in my setup but
r_vmcircbuf_sysv_shm_factory aborts in make check.

Now I don't know if gnuradio will use the working factory, a random factory or 
the non-working factory.
