If you're working from a clean git clone, I use this for working with just
owcapi:
$ autoreconf -i
$ ./configure CFLAGS='-g -O0' --prefix=$HOME/opt/owfs
--disable-{zero,ow{perl,python,php,tcl}}
$ make
$ make -k install
This lets me ignore most of the language binding dependencies, and ignore some
hardcoded install paths.

I have been working on some issues I've found in libow, and have seen similair
symptoms. There's some race conditions that, if it doesn't outright crash,
causes random failures elsewhere. I have a patch that resolves these issues
here:
https://gitlab.com/justinbrewer/owfs/commit/0234a2cecb56d0b6ca4d20a6100a2d2b2ba6bffb.patch
I was planning on submitting a pull request in the next day or so, but I think
this patch help you.
