Fwd: sip6: fails to process __delattr__ in libarcus 5.0~beta (works with sip 6.5)

[Dmitry Shachnev]

Hi Phil!

Thank you for your previous reply. I updated Debian package to 2022-05-13
snapshot (except for one commit which changed ABI). And now I received this
bug report.

When trying to build libArcus 5.0~beta (part of the Cura slicer),
sip-build 6.6 produces bogus C++ output that fails to compile:

sip-build 6.5 in testing produces correct output and the project builds
fine.  This looks like another instance of problems with the new parser
in 6.6.
