double free or corruption (out)

[tiffuhu]

After running extractHAIRS and LinkedFragments.py successfully, I have been running HAPCUT2 that gives the "double free or corruption (out)" error. Both the haplotype block file and the phased VCF are output successfully and have results within the files, but I am still getting the error. Is this something that is cause for concern? I have provided the readout below.

This looks like an error in freeing the memory at the end of the program. The output should not be affected. If possible, could you run the code using gdb and share the output. This will help figure out the problematic line(s) in the code. Thanks.
