Shoud be fixed - see here https://github.com/solvespace/solvespace/pull/1611#issuecomment-3172851903 @rcarmo @ad-si please test.

This seems neither OpenMP nor ASan specific. On my machine (i7-1355U, MSVC 2019 16.11.49, Win11) the build mode makes a difference. Build | bits | OpenMP | result -------------- |...

Aha! Thank you @iscgar in this case I know what it is - it is this problem https://github.com/solvespace/solvespace/issues/1091#issuecomment-903661168 See also the following comments particularly the one from Jwesthues https://github.com/solvespace/solvespace/issues/1091#issuecomment-904048397 I...
