[SOLVED] qutebrowser / python-yaml segmentation fault

Hi,
I updated my system after not using it for a few month. Now qutebrowser segmentation faults.
I tried to make a bugreport on archlinux32.org but it looks like i don't have the privilege to do so.
Could someone please report this bug for me?
Here is the stacktrace:

python-yaml 5.4.1.1-2.0
libyaml 0.2.5-1.1
python 3.9.7-2.1
glibc 2.33-5.1

I'm on the branch pentium4 and my cpu supports cmov, mmx, see, and sse2

Please help me with this issue.

Re: [SOLVED] qutebrowser / python-yaml segmentation fault

FWIW, I have a relatively simple python tool which loads in a couple of yaml config files when I load it.  I have the same packages installed except my kernel isn't quite as new, but it's working for me in that case.  That doesn't help your problem which looks genuine to me.  Unfortunately I don't have a login to the bug tracker at present so I can't raise your bug right now.

thank you for your reply. could you please try the following on your system:
-open terminal
-python3
-import yaml
-yaml.CLoader(None)
This throws a TypeError on my 64bit system, but it segfaults on my 32 bit system.

Re: [SOLVED] qutebrowser / python-yaml segmentation fault

Yes, same here.  That at least does segfault, and the dump it produces looks very similar to the one you posted above.

Re: [SOLVED] qutebrowser / python-yaml segmentation fault

This sounds like a libffi issue in Python itself. Currently libffi.so.8 is in stable, the whole load of Python still in testing.
I pushed the python3 and python interpreters, hope this fixed it.
The bug is https://bugs.archlinux32.org/index.php? … ask_id=213, I added your comments there..

Thanks for reporting. :-)

Re: [SOLVED] qutebrowser / python-yaml segmentation fault

mmh. already in stable.
Don't tell me I have to rebuild all python module with libffi.. not to mention that those dependencies don't show in the dependencies of the package
because 'python'/'python2' provides the bindings..

Re: [SOLVED] qutebrowser / python-yaml segmentation fault

Indeed, with python-yaml 5.4.1.1-2.1 I get now:


Python 3.9.7 (default, Oct 22 2021, 09:28:30)
[GCC 11.1.0] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> import yaml
>>> yaml.CLoader(None)
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/usr/lib/python3.9/site-packages/yaml/cyaml.py", line 47, in __init__
    CParser.__init__(self, stream)
  File "yaml/_yaml.pyx", line 303, in yaml._yaml.CParser.__init__
TypeError: a string or stream input is required
>>>
>>>

I triggered all Python modules for a rebuild..
