Hi,

I've been running ANTs Atropos using the downloaded GitHub release binary ants-2.5.0-macos-12-X64-clang.zip for my Mac Studio, Apple M1 Max, macOS 14.1.1:

noglob Atropos -d 3 -x brainmask.nii.gz \
-c [ 200,0.0005 ] \
-a diff.nii.gz \
-i kmeans[ 2 ] \
-s 1x2 \
-k HistogramParzenWindows[ 1,32 ] \
-m [ 0.1,1x1x1 ] \
-o [ tmpSegmentation.nii.gz,posteriors%d.nii.gz ] \
-r 1 -p Socrates[ 0 ]

However, it crashes with the following terminal output:

Atropos(6030,0x30f7b5000) malloc: *** error for object 0x600002380f00: pointer being freed was not allocated
Atropos(6030,0x30f7b5000) malloc: *** set a breakpoint in malloc_error_break to debug
zsh: abort noglob Atropos -d 3 -x VISIT01/T1_brainmask.nii.gz -c [ 200,0.0005 ] -a -i

On the other hand, I had no problems with the ANTs 2.4.2 version (also downloaded GitHub release binary).
