Package: clang-10

Severity: normal
Dear Maintainer,
I think clang-10 package does misses correct dependency information.

My guess is it doesn't work becasue of libclang-cpp10 and clang-10 versions not
matching, and ABI not beying stable (which is not a problem).
Maybe there should be more tight version dependency from clang-10 to
libclang-cpp10 ?
At the moment clang-10 dependencies looks like this:
Package: clang-10
Version: 1:10~svn374655-1~exp1
Depends: libc6 (>= 2.14), libclang-cpp10, libgcc1 (>= 1:3.0), libllvm10 (>=
1:9~svn298832-1~),
libstdc++6 (>= 9), libstdc++-8-dev, libgcc-8-dev, libobjc-8-dev,
libclang-common-10-dev (= 1:10~svn374655-1~exp1),
libclang1-10 (= 1:10~svn374655-1~exp1), libc6-dev, binutils
Notice however that there is no versioning of libclang-cpp10. Only libclang1-10
Manually updating libclang-cpp10 using apt install -t experimental
libclang-cpp10, does resolve the problem.
This bug also affects clang-9 (depends on unversioned libclang-cpp9), but
not clang-8 (doesn't use libclang-cpp, only on versioned libclang1-18)
Best regards,
Witold
