Moreover, I appreciate that for each session I start there is a file
created with strange char name (&, , º, ', and other rubbish), different
for each session (so I have many of them). All of them contain
"gr_vmcircbuf_createfilemapping_factory, only this word. I guess maybe
there is a sprintf("%s") with rubbish, I do not know.

Any guidance will be appreciated.
