Bug-Description:
|
|
|
|
If an application uses readline's event hook, it is called while waiting for
|
|
input. There is a bug in the function that waits for available input that
|
|
causes it not to read that input under certain circumstances, resulting in
|
|
a loop where the event hook continues to be called, but there is no input
|
|
to stop it.
|
|
|
|
Patch (apply with `patch -p0'):
