--- Comment #3 from Vladimir Panteleev <dlang-bugzilla at thecybershadow.net> ---
It's in the issue title. On 2.103.1, the full output is:

core.exception.AssertError@/home/vladimir/data/software/dmd/dmd.2.103.1.linux/dmd2/linux/bin64/../../src/phobos/std/algorithm/mutation.d(1427):
Cannot move object of type Tuple with internal pointer unless `opPostMove` is
defined.
