Thanks for the tips, Warren. I will follow up on this in about 4 weeks when I get back to that workstation to do the implied experiments. > WSL2 uses an actual Linux kernel with regular Linux filesystems. That's why I was surprised at the failure, in part. The other part is that, at times, it has passed the whole suite of SQLite's TCL tests except for ones doing full precision FP value comparisons. This makes me think I must have switched that system back to WSL1 for some reason and forgotten to switch it back.
