Ok, so this particular test must have been skipped. It's not possible
that the test ran and passed since the issue is a very abrupt abort().

Try to run 'make check-block' and watch for the test 181. Or run from the
build directory: ./tests/qemu-iotests/check -qcow2 181

I started a gitlab pipeline with this code to rule out anything in my
own setup. Let's see:
https://gitlab.com/farosas/qemu/-/pipelines/1032002487

> [root@06f1b38a5d6a build]# make check
> /rpmbuild/SOURCES/qemu/build/pyvenv/bin/meson test  --no-rebuild -t 0  
> --num-processes 1 --print-errorlogs

hmm, hopefuly you're not using an outdated tree that you fetched from
the rpm source package.

To run a pipeline on Gitlab you need to push a branch to your QEMU fork
and trigger the pipeline via the Build->Pipelines->Run Pipeline
option. Choose the branch from the dropdown and input an environment
variable with key: QEMU_CI and value: 2 in the Variables field.

We have documentation on how to do that directly from the command line
here: https://www.qemu.org/docs/master/devel/ci.html
