Dear Sparse Maintainers,

I am copying the bug report[1] to the mailing list as per the email below.

Building sparse-llvm against LLVM 15 results in test failures due to the
segmentation faults[2].
Would it be possible to consider an attached patch to migrate the
sparse-llvm source code to the opaque pointers [3] at some point?

Best Regards,
 Vladimir.
