Estimated hours taken: 2 Fix a bug that Tom reported where calling solutions/3 with an equivalence type caused a crash in deep_copy(). runtime/deep_copy.c: Fix a bug in the copying of equivalence types and no_tag types. It was using `entry_value' instead of `entry_value[1]'. tests/hard_coded/Mmake: tests/hard_coded/.cvsignore: tests/hard_coded/deep_copy_bug.m: tests/hard_coded/deep_copy_bug.exp: Add a regression test for this bug.
