>Description:
process substitution gives garbled results
while read line ; do echo $line ; done < <(cat /etc/passwd)
For some reason under 5.3 it loses a chunk off the front of each line producing garbage results
>How-To-Repeat:
while read line ; do echo $line ; done < <(cat /etc/passwd)
>Fix:
Not sure if this is a bash issue or a kernel issue but this is not a problem on any of the 4.x boxes I've tried it on. Also, the version of bash is not a factor.. it happens with 2.x and 3.x
