In line with @remi.andreoli988’s findings in this topic I am having trouble using the latest version of sen2cor, version 2.12.03.
While sen2cor 2.11 works without issue, sen2cor 2.12.03 fails with the error ‘Illegal instruction’, likely related to a difference between the compilation and execution platform.
For example:
/home/adriaan/opt/Sen2Cor-02.12.03-Linux64/bin/L2A_Process --work_dir _WORK --processing_baseline 92.12 --processing_centre GEOT --archiving_centre GEOT --GIP_L2A /mnt/adriaan-ahn/SentinelNL/S2_L2A_GIPP_212.xm
l ./S2A_MSIL1C_20150822T104036_N0500_R008_T31UFS_20231010T063709.SAFE
Results in a crash, as shown below:

Illegal instruction
The machine is based on an Intel i5-2400 and runs Debian 12. The processor is dated, but is able to keep up with the acquisitions. It appears, however, that sen2cor 2.12.03 was compiled with instructions unavailable on this processor.
