Bug description:
I am using Ubuntu 20.04 for development and has hit a bug in bash 5.0
patch 16.
I can't reproduce it in pure bash, but with bats from
https://github.com/bats-core/bats-core/ it is very easy to repro:
```
# cat << EOF > ya.bats
check() {
echo "check $@"
ls -l /proc/self/fd
}
@test "here file" {
check -p <(echo "hey")
false
}
EOF
$ bats ya.bats
```
Normally the output should contain the line
lr-x------ 1 kir kir 64 May 14 02:01 63 -> pipe:[4616918]
which is a result of a "here file" created by bash via <(echo "hey").
In my testing, about 50% of runs don't have /dev/fd/63 listed.
I found out this is a manifest of a bug introduced in bash 5.0 patch
16 (see http://ftp.gnu.org/gnu/bash/bash-5.0-patches/bash50-016)
The bug is fixed in 5.0 patch 17 (see
http://ftp.gnu.org/gnu/bash/bash-5.0-patches/bash50-017).
Please update bash to patchlevel 17.
