Hi,
here is a test data set that causes a segmentation fault running on Ubuntu 20.04.4 LTS:
0_decoy.csv
1_decoy.csv
But this one works:
5_decoy.csv

percolator-v3-06-linux-amd64.deb

$ percolator 0_decoy.csv 
Segmentation fault (core dumped)
$ percolator 1_decoy.csv 
Segmentation fault (core dumped)

But this works

$ percolator 5_decoy.csv 
Protein decoy-preix used is random_seq_378
All files have been read
...

Actually, Percolator complains about too good separation but that is expected with this data set

percolator-v3-05-linux-amd64.deb

$ percolator 0_decoy.csv 
...
Exception caught: Error: no decoy PSMs were provided.

✔️ Percolator notices that there are no decoys

$ percolator 1_decoy.csv 
...
$ percolator 5_decoy.csv 
...

✔️ Percolator works
