Some of my bash scripts, particularly ones that are #!/bin/bash --posix
trigger a nasty warning when I have SHELLOPTS=igncr set in my ~/.zshrc:

rkitover AT eeebox ~/src/scala % echo $SHELLOPTS
igncr
rkitover AT eeebox ~/src/scala % bash --posix
bash: SHELLOPTS: readonly variable

this is rather unsightly so I have turned off SHELLOPTS for now.

Is this a bug? If so, is a fix possible?
