@ZGHHGZ thanks for the report.

I noticed this issue recently as well. The process segfaults somewhere around the secondary unwrapping step when run in tiled mode with multiprocessing. I think it's a bug in the isce3 implementation since I wasn't able to reproduce the issue when using the standalone SNAPHU software. But I'm not sure what exactly is the cause yet.
