Hello,

I believe this patch is responsible for ptests failures:
  qemux86-64-ptest debian12-vk-8 wrynose completed at 2026-09-14 22:47:23+00:00
  https://autobuilder.yoctoproject.org/valkyrie/?#/builders/73/builds/4557

  qemux86-64-musl-ptest fedora43-vk-2 wrynose completed at 2026-09-14 
22:48:49+00:00
  https://autobuilder.yoctoproject.org/valkyrie/?#/builders/110/builds/1185

Failed ptests:
{'curl': ['1105_-_HTTP_with_cookie_parser_and_header_recording_-_output']}

I could reproduce this locally with 
bitbake core-image-ptest-curl && bitbake core-image-ptest-curl -c testimage

Can you look into this?

In the meantime, I'll keep 1-3,5-6/6 in my branch.
