Hello Amber Community,

I am running into an issue with cpptraj when running the following commands:

parm example.parm7
trajin parent.ncrst
trajin seg.nc

<I do other commands here including analysis and stripping away waters, but they aren't necessary to reproduce the error>

trajout seg_stripped.nc cdf start 2
go
quit

Every time I try this no matter what the topology and trajectory files are, I get a segmentation fault. I am using the latest version of ambertools. Using only one trajin does not produce the error.

Thanks,
Stephen
