throws a domain error, even thoug I guard against negative numbers

But if (lensq > FLT_EPSILON) is too late as earlier dx*dx + dy*dy + dz*dz caused int overflow. "and indeed overflow, causing lensq to be negative" - which is undefined behavior UB.

Compiler can take advantage that sqrtf(lensq) can always work because it can assume dx*dx + dy*dy + dz*dz >= 0 and so lensq >= 0.0f.

Get rid of UB.

I have figured it out,

Instead of assigning to df, only assign to the columns you want to sort.

Is this a safe practice for getline-sscanf inside a function or should I initialize the string and nbytes within this function. (?)

No. It is not safe. Code instead could initialize string = NULL, nbytes = 0 within this function and free string when done.

As coded, the prior values of nbytes and my_string are needed to be specified as well the updated values after the getline() call needs to update boxdim() calling arguments. This does not occur as main() passes copies of string, nbytes.

Not checking the return values of scanf(), it is also "unsafe".

Alternative

You have one too many $unwind.

Updated your aggregation query to remove extra $unwindstage and added $group to count the results from $project stage.

Instead of using getValues use as.data.frame to convert raster to a dataframe.

Hmmm, When I copied you code, it also did not work for me. So I cleaned it up a lot, and now it works... But I don't know what I changed which made it to work. Maybe someone else can help? It's probably has to do with the arithmetic.
