Link to stackoverflow:

https://stackoverflow.com/questions/58217308/fixing-addresssanitizer-strcpy-param-overlap-with-memmove

Needs to be implemented in the code.

[darked89]

While above stackoverflow "fixes" the reported error, the problem is with zero sized destination. No space to store anything in zero bit.

[darked89]

The problem does not show up unless the fasta sequence (contig?) is way above 2399940
nucleotides.
