* Null checks on return from std::make_shared are unnecessary... ... instead std::bad_alloc would be thrown in case of memory exhaustion, which we don't try to recover from. * Restore uses of the mayThrow arguments in Sequence... ... that became unused at commit d39590cf41e1e1eac02fc52d88a1ad018824f77b. It's important to ignore exceptions from SampleBlocks when only displaying, not editing or playing, and just treat missing data as silence. Pass the boolean into the SampleBlock routines. But the throwing of exceptions is not yet implemented. * SampleBlockFactory functions guaranteed to return non-null or throw... ... which corrects Sequence.cpp, which was assuming non-null results. This supplies the throw statements that the previous commit comment says were still lacking. This corrects the absence of checks of returns from sql_bind_... function calls in SqliteSampleBlock.cpp. (Other calls remain to be checked elsewhere.) User visible error messages, carried by the exceptions, might be improved. * Restore the try/catch in AutoSaveFile::Decode... ... which was introduced at 2ba17c78d6758c2f64f2ccfec9af0c537525cea4 but removed at d39590cf41e1e1eac02fc52d88a1ad018824f77b, yet without removing the throw statement which left the program vulnerable to abrupt termination instead of graceful failure, when uninterpretable auto save contents are detected.
