* [Description]
|
||
|
|
*
|
||
|
|
* Check wait4(INT_MIN, ...) is not allowed. The pid is negated before
|
||
|
|
* searching for a group with that pid. Negating INT_MIN is not
|
||
|
|
* defined so UBSAN will be triggered if enabled. Also see kill13.
|
||
|
|
*
|
||
|
|
* If the bug is present, but UBSAN is not enabled, then it should
|
||
|
|
* result in ECHILD.
