The same assertion failure is also described in https://www.gnu.org/software/hurd/open_issues/ext2fs_libports_reference_counting_assertion.html

It was reputedly fixed as "ext2fs: fix pager use-after-free" in May 2016: https://git.sceen.net/hurd/hurd.git/commit/?id=60d14f5b3c4ea27af6f4220a15947c328bc888ee

Package: Hurd
Version: N/A
Severity: normal

I just got this crash:

ext2fs.static: ../../libports/port-ref.c:31: ports_port_ref:
Assertion 'pi->refcnt || pi->weakrefcnt' failed.

It seems it's not reproducible.

If you ever do manage to reproduce it, the stack trace from here will tell
us a lot about what is going wrong. This assert means that the caller
should not have been calling ports_port_ref, i.e. the bug is almost
certainly in ext2fs (or one of the other libraries) and not in libports itself.

I just got this in the middle of the second glibc build (I also did some
other stuff before that, so it is quite rare). Of course, I had no debugger
attached. It was also ext2fs.static, although I was building on a different
filesystem.

Of course, this doesn't help us a bit.
