Hi!  It looks like one of the tests in package `encfs` consistently segfaults
in the version of Guix shown below:

```
$ LANG=C guix describe
Generation 56   May 02 2023 11:25:26    (current)
  guix 3f8c489
    repository URL: https://git.savannah.gnu.org/git/guix.git
    branch: master
    commit: 3f8c4899a9a67bb509a603bd21dcfcfab88c0e8e
```

This is the final part of the build log:

```

The following tests FAILED:
	  1 - unit (SEGFAULT)
Errors while running CTest
make: *** [Makefile:94: test] Error 8

Test suite failed, dumping logs.
error: in phase 'check': uncaught exception:
%exception #<&invoke-error program: "make" arguments: ("test" "-j" "4") exit-status: 2 term-signal: #f stop-signal: #f> 
phase `check' failed after 0.0 seconds
command "make" "test" "-j" "4" failed with status 2
```

I saw a couple of encfs issues regarding segfaults in tests, but I don't think
they're related: <https://github.com/vgough/encfs/issues/378>
<https://github.com/vgough/encfs/issues/600>

Thanks a lot, and cheers!
