External Email - Use Caution        

While I do no know and have not looked at the source code in question, if you lookup that error online, one explanation is memory corruption is happening by writing beyond the end of allocated memory, e.g., by using free(g) incorrectly.

However the code is written, an issue with memory allocation might be exacerbated depending upon how memory management is done on the platform.  Memory management on MacOS is extremely aggressive about swapping out to disk well before physical RAM is in danger of being underrun.   Or it is virtually impossible to run out of physical RAM on macOS though things may slow down to a crawl and/or thrash.   It might be informative to know if you are hitting memory limits in the cluster and in the container (where it crashes) - but for some reason not on MacOS.  Similarly, it would be interesting to know if the memory error occurs when run on a stand alone linux workstation.

So the same input volume will sometimes succeed and sometimes fail depending upon the platform?

Hello,
     I am trying to process several images with MiDeFace but running into issues with memory and uncaught exceptions.

Of 50 images, about half are processed successfully. On the other half MiDeFace fails consistently. However, whether the images fail seems to depend on the platform. Here's what I've tried
  • Fails
    • freesurfer-linux-centos7_x86_64-7.4.0.tar.gz install on HPC, CentOS Linux release 7.9.2009 (Core)
    • freesurfer-linux-centos7_x86_64-7.3.2.tar.gz install on HPC, CentOS Linux release 7.9.2009 (Core)
    • Apptainer image from docker://freesurfer/freesurfer:7.3.2, (this is built on CentOS:7) run on HPC
    • Docker image from docker://freesurfer/freesurfer:7.3.2, (this is built on CentOS:7) Apple M1 Pro; 13.3.1
    • Custom docker image (below), built and run on Apple M1 Pro; 13.3.1
  • Succeeds
    • freesurfer-darwin-macOS-7.4.0.pkg, installed and run on Apple M1 Pro; 13.3.1

So, I'm not sure whether this is a bug or something that I need to configure differently.

Example apptainer command

$ apptainer exec -e -B $(pwd):/data docker://freesurfer/freesurfer:7.3.2 mideface --i /data/volume.nii.gz --o /data/defaced.nii.gz --odir /data/qa

Example docker command

> docker run --rm -it -v $(pwd):/data freesurfer/freesurfer:7.3.2 mideface --i /data/volume.nii.gz --o /data/defaced.nii.gz --odir /data/qa


Example "bare" command

> mideface --i volume.nii.gz --o defaced.nii.gz --odir qa

On the CentOS runs, the error is
