bug in bash

[Quốc Trị Đỗ]

Hi,

I found a bug when i tried with syntax <(cmd). this is an example
cat <(wc -l) < bk

You can follow this command, then you have bugs. I think because you
created a fork getting inside in the parenthesis and the main process do <
bk. They work parallel. Because of that,  yeah.
At least, I tried this here on this campus, at 42Heilbronn - Germany.

How to fix it? It doesn't last that long. After a while, it will show "wc:
stdin: read: Input/output error". Or we can ctrl C.
