|Hi,
|
||
|
|
|
|
||
|
|
|I've got another bug report from one Fedora user. When whence builtin is used
|
||
|
|
|with -q option it hangs. Whence was modified a lot between 2008-02-02 and
|
||
|
|
|2008-07-25. New version uses while(pp) loop but for Q_FLAG pp never changes
|
||
|
|
|causing ksh loop forever. I've just added pp = 0 to Q_FLAG if-section and it
|
||
|
|
|seems working fine:

|Btw, when looking in the code it seems tofree variable is never checked when
|
||
|
|
|Q_FLAG is used and also in the loop this value is sometimes set to 1, but
|
||
|
|
|never zeroed once it is set, is it expected?
