11 Bug-Description: |
|
12 |
|
13 When the `read' builtin times out after the timeout specified with -t is |
|
14 exceeded, it does not reset the flags that tell signal handlers to process |
|
15 signals immediately instead of deferring their handling. This can result |
|
16 in unsafe functions being called from signal handlers, which can cause bash |
|
17 to hang or dump core. |
