[windows] AutoLevel algorithm instability #35

Closed bgallois closed 2 years ago

bgallois commented 2 years ago

Several runs of the AutoLevel algorithm produce several results on Windows.
Mac and Linux versions are converging on the same values all the time.
Probably related to #34.

bgallois commented 2 years ago

On Windows and compiled with MinGW_64 and MSVC2019 the algorithm is stable and gives the same result with the release flag as the Linux version except for the normalization angle that can be slightly different with a precision of ~10e-2. Convergence was fixed with 729c5d31ab30555c9bb80b0efb4259c5ed9de76e when the correct release flag was added to the deployed version.
