bedtools complement hangs when using -i <(cmd)

[outpaddling]

Hit an issue with the test suite, where bedtools complement doesn't work with a process substitution following -i.

Here's a minimal script that reproduces the issue:

#!/usr/bin/env bash

set -x

# This works
cat <(echo -e "chr1\t0\t1") <(echo -e "chr1\t20")

# This works
echo -e "chr1\t0\t1" > temp
bedtools complement \
	-i temp \
	-g <(echo -e "chr1\t20")

# This hangs, but if I determine the name of the fifo and manually run
# echo -e "chr1\t0\t1" > /tmp/fifo-name, it finishes successfully
bedtools complement \
	-i <(echo -e "chr1\t0\t1") \
	-g <(echo -e "chr1\t20")

Anyone else seeing this?

Any suggestions where in the source code it might be getting stuck? I can add some debug code to gather more info if I know where it's opening and reading the file.

So far I've found my way to addInputFile() and verified that the fifo name is correct.

Thanks.
