Bug description:
  I have now applied a patch which fixes the webkit2gtk build on all
  architectures except for armhf.

  https://launchpad.net/ubuntu/+source/webkit2gtk/2.48.0-1ubuntu3

  Although I reported a webkitgtk bug for tracking, this appears to be a
  llvm bug.

  Workaround
  ====================
  For armhf, I'm now using clang-19 instead of the default clang.
