Here is a reduced testcase for Olga's problem:
-- snip --
export PATH='/not/here/path:/bin:/usr/bin'
# Get terminal size and put values into a compound variable with the integer
# members "columns" and "lines"
function get_term_size
{
nameref rect=$1
rect.columns=${ tput cols ; } || return 1
rect.lines=${ tput lines ; } || return 1
return 0
}
compound r
get_term_size r || print 'FAIL'
print -C r
-- snip --
The testcase fails like this:
-- snip --
$ ksh /tmp/chickenterror.sh
/tmp/chickenterror.sh[16]: get_term_size[10]: tput: not found [No such
file or directory]
FAIL
(columns=169;lines='')
-- snip --
After some digging it turned out that replacing '/not/here/path' with
'/tmp' fixes the problem... AFAIK this looks like having an element in
PATH which points to a non-existing directory causes the failure...

Bye,
Roland
