    4747Note that the two candidates for the matrix product here are congruent modulo 1103, which is prime.  If you rerun the code with verbose logging, using set_verbose(2), then every time it fails the two candidates for the matrix product are congruent modulo the prime being used in the multi-modular algorithm.  Thus I suspect that the Chinese Remainder Theorem code in sage/ext/multi_modular.pyx is not handling a corner case properly.
