Figured it out, so you need to place a clause where someone should first figure out the version glibc they are using: ldd --version, then proceed to code at line 90 and rename the member name of size of struct malloc_chunk according to the glibc version.

GlibC code repo of different versions

# before
gdb.parse_and_eval("((struct malloc_chunk)*{}).size".format(hex(current_chunk_address)))

# after my case glibc version 2.27
gdb.parse_and_eval("((struct malloc_chunk)*{}).mchunk_size".format(hex(current_chunk_address)))

Hey! :) Sorry for the late reply ;) I haven't touched the repo in 3 years but it's on my TODO list to update everything that it works again. Thanks for your solution! I will integrate it ;) Cheers, Martin
