--- Comment #2 from Frantisek Skala <fun...@gmail.com> ---
I've tried this with the latest stable LLVM clang+lld (12.0). The reproducer
needs a slight modification to work, but valgrind is still broken when using
LLD. Make regtest results in the following output:

-- Finished tests in exp-bbv/tests/amd64-linux -------------------------

== 698 tests, 157 stderr failures, 19 stdout failures, 0 stderrB failures, 0
stdoutB failures, 3 post failures ==

As can be seen from for example
./memcheck/tests/vbit-test/vbit-test.stderr.out, the UME 22 error is still
there:

valgrind: mmap(0x........, 5009408) failed in UME with error 22 (Invalid
argument).
valgrind: this can be caused by executables with very large text, data or bss
segments.

It seems that valgrind is incompatible with LLVM 12, is that expected? Is this
likely to be a LLVM bug, or a Valgrind bug?
