Yeah, looks like it. Works on linux though...
By the way, this is bash-3.2.25 on FreeBSD/x86 7.
bash-4.0.33_2 on x86 6.3.
Is this what you've intended the prompt to look like?
I'm using an awk script to truncate any pwd that's too long.
get_short_pwd()
{
# The actual max length is max_len + the length of trunc_symbol
local max_length=$1
local trunc_symbol=...
if [ -z $max_length ]; then
max_length=20
fi
if [ $PWD != $OLDPWD ]; then
SHORT_PWD=$(awk BEGIN {
path = ENVIRON[\PWD\]
home = ENVIRON[\HOME\]
home_len = length(home)
max_len = $max_length
sym_len = length(\$trunc_symbol\)
if(substr(path, 0, home_len) == home) {
path = sprintf(\~%s\, substr(path, home_len + 1))
}
path_len = length(path)
if (path_len max_len) {
path = sprintf(\%s%s\, \$trunc_symbol\, substr(path,
path_len + sym_len - max_len + 1))
}
print path
})
OLDPWD=${PWD}
fi
}
This is called via a build_prompt() function in my .bashrc. I guess I'll echo
out some variables there and see what's happening.
FTR this did work, and then I updated bash in ports.

I'm wondering if this is a bash bug on bsd, or if I'm doing something wrong.
Your PS1 seems to include ${SHORT_PWD}, a variable. It seems
that it is not updated immediately after the cd command.
Has anyone seen this?
No. I don't have any path information at all when I use your PS1.

By the way, this is bash-3.2.25 on FreeBSD/x86 7.
But I tried to replace the ${SHORT_PWD} by the \w control
sequence (as mentioned in man bash). This is the result:
$ export
PS1=\[\033[1;32m\]\[\033[0;36m\]\u\[\033[1;32...@\[\033[0;36m\]\h\[\033[1;32m\]:\[\033[0;37m\]\w\[\033[1;32m\]$\[\033[0;37m\]
p...@r55:~$ cd /etc
p...@r55:/etc$ cd /usr/src/sys
p...@r55:/usr/src/sys$
And the \W short form:
p...@r55:/usr/src/sys$ export
PS1=\[\033[1;32m\]\[\033[0;36m\]\u\[\033[1;32...@\[\033[0;36m\]\h\[\033[1;32m\]:\[\033[0;37m\]\w\[\033[1;32m\]$\[\033[0;37m\]
p...@r55:sys$ cd /bin
p...@r55:bin$ cd /usr/local
p...@r55:local$
The username and hostname are cyan, @, : and $ are bright green.
Is this what you've intended the prompt to look like?
