Fixed in 8db4ebb0cd9bfdcf1aea63eb8d20eb6af0c87c93. \o/ It makes ‘--with-debug-info’ more practical. The difficulty is to find out where the difference is and what piece of code introduced a non-eq?-but-equal package. Likewise, the test suite catches corner cases that can take a while to address. Related to that, commit 6b4663363c061071c10209f71aed1017a241af6c deletes duplicates in ‘bag->derivation’, which should make the whole thing less sensitive to the introduction of non-eq?-but-equal packages in the graph.
