default_gdb_init has this:
# Unlike most tests, we have a small number of tests that generate
# a very large amount of output. We therefore increase the expect
# buffer size to be able to contain the entire test output. This
# is especially needed by gdb.base/info-macros.exp.
match_max -d 65536
# Also set this value for the currently running GDB.
match_max [match_max -d]
It's the second match_max that is erroring. As that call does not
specify an explicit channel name with -i, expect defaults to
$spawn_id, which is pointing at a channel that is already gone. (If
the spawn_id variable is not set, match_max defaults to
$user_spawn_id / stdin/out).
