Bash Version: 4.0
Patch Level: 33
Release Status: release
Description:
bash 4.0 fails to parse a function that's parsed successfully by dash(1) as
well as older versions of bash (3.1, 3.2):
[...@boost:pts/6 ~> cat inet
swap32_posix()
{
local funcname=swap32_posix
local arg
for arg in "$@"; do
echo $((
($arg & 4278190080) >> 24 |
($arg & 16711680) >> 8 |
($arg & 65280) << 8 |
($arg & 255) << 24
))
done
}
[...@boost:pts/6 ~> bash -n inet
inet: line 6: unexpected EOF while looking for matching `)'
inet: line 14: syntax error: unexpected end of file
[...@boost:pts/6 ~> dash -n inet
[...@boost:pts/6 ~>
Repeat-By:
This affects the *left* bit shift operator, but *not* the right bit shift
operator:
[...@boost:pts/6 ~> cat left.sh
echo $((2 << 1
))
[...@boost:pts/6 ~> bash -n left.sh
left.sh: line 1: unexpected EOF while looking for matching `)'
left.sh: line 3: syntax error: unexpected end of file
[...@boost:pts/6 ~> cat right.sh
echo $((1 >> 2
))
[...@boost:pts/6 ~> bash -n right.sh
[...@boost:pts/6 ~>
