> In short: multithreading is hard So true! With the introduction of tsan things are a little less bad, but tsan is still a tool with plenty of false positives and false negatives. And that assumes that a particular issue is covered by the tests being run under tsan.

Thanks for the announcement, Even! I wonder if we should track such issues in a list? Or maybe give them a unique GitHub label? We don't plan to release a 3.6.5, correct? I'm going to make a Rasterio post release that patches 3.6.4 by tomorrow: https://github.com/rasterio/rasterio/issues/2943.

Hi, For GDAL 3.6.0 to 3.7.2, use of multi-threaded GTiff compression+decompression, in particular within the same file, as for example in a "gdalwarp -co COMPRESS=... -co NUM_THREADS=..." workflow can lead to deadlocks (process stalled forever) and/or data corruption (sometimes without
