Bug#1057899: libc++abi-18-dev has an undeclared file conflict on /usr/lib/x86_64-linux-gnu/libc++experimental.a

[Helmut Grohne]

Package: libc++abi-18-dev
Version: 1:18~++20231203063627+9f78edbd20ed-1~exp1
Severity: serious
User: debian-qa at lists.debian.org
Usertags: fileconflict
Control: affects -1 + libc++-17-dev

libc++abi-18-dev has an undeclared file conflict. This may result in an
unpack error from dpkg.

The file /usr/lib/x86_64-linux-gnu/libc++experimental.a is contained in
the packages
 * libc++-17-dev/1:17.0.6-2 as present in unstable
 * libc++abi-18-dev/1:18~++20231203063627+9f78edbd20ed-1~exp1 as present in experimental

These packages can be unpacked concurrently, because there is no
relevant Replaces or Conflicts relation. Attempting to unpack these
packages concurrently results in an unpack error from dpkg, because none
of the packages installs a diversion for the affected file.

Kind regards
