Re: [sage-devel] bug in cuspidal subspace of ModularSymbols with character over p-adic field

Thanks for the example! I'm hoping to work on p-adic linear algebra over the next few months, and having examples of failures is always useful to test improvements. But that's a pretty impressive discrepancy, between 1345499989865120018402 and 0. I don't have time to look into it now, but I woul
