[oroppas]

I've got this truffle exception while dealing with GraalPy, so let me first report it here. Please let me know if there is a better place to report.

Let's assume venv is already activated for GraalPy. In order to replicate the error, Cython needs to be installed by

graalpy -m pip install Cython

as Cython is required by lxml

Then follow the steps below:

git clone https://github.com/lxml/lxml
cd lxml
make
make test

Here's the detailed log:

[msimacek]

The UnsupportedSpecializationException is currently just a secondary symptom of Sulong (the LLVM runtime) crashes. The real cause is Invalid argument to polyglot builtin part. I've already encountered the same issue (I was also testing lxml) few weeks ago and reported it to Sulong team (it's an issue on their end).

[msimacek]

I just merged several fixes for lxml and now the tests shouldn't crash anymore (some tests still fail, but there should be no more hard crashes).

Awesome. Thanks!
