Did you change line 447 of FloppyTail.cc to read “false” instead of “true”? (The documentation explains the problem but still says the line number from 3.1 instead of 3.2; it’s been fixed for 3.3). It’s not clear that that’s your problem, it looks like your segfault occurs earlier, but that’s far-and-away the most likely issue.

FloppyTail has proven to be vastly more popular than I expected it to be, so I’ve been tweaking out some things from its original paper (like the analysis suite that is likely causing your crash) to make it more compatible with other uses. The 3.3 release will fully support N-terminal tails and “internal” tails.

If that’s not the problem, then it’s probably related to whatever is causing those unexpected “Warning: no movable positions in SmallMover!” warnings. What are your values for the flags controlling the flexible region (start, end, and chain), and what are the PDB residue IDs for those?
