panic: runtime error: slice bounds out of range

[mernst]

I am using pt version 2.1.5 downloaded from https://github.com/monochromegane/the_platinum_searcher/releases .

% pt --version
pt version 2.1.5
% uname -a
Linux godwit.cs.washington.edu 4.4.110-1.el7.elrepo.x86_64 #1 SMP Fri Jan 5 11:35:48 EST 2018 x86_64 x86_64 x86_64 GNU/Linux

When I ran
pt --smart-case --global-gitignore --home-ptignore --hidden -e --nogroup --color -- travis_wait .
pt crashed with
panic: runtime error: slice bounds out of range
Below is the complete output, which includes the stack trace.
