| Summary | 0002067: Divide by zero in SDFGenerator | ||||
| Description | However, we then hit a divide by zero in SDFGenerator.cpp, line 348:
In this case, t.x was zero. It’s not urgent – we’ve just disabled FP exceptions whenever we call into Noesis, so this is not blocking us. We’d just like to be able to remove this at some point in the future I’ve added a check for zero in this case, and set it to a small value, and it prevents the crash. | ||||
