BASH PATCH REPORT

=================

|
Bash-Release: 3.2
|
|
Patch-ID: bash32-018
|

|
|
Bug-Reported-by: osicka@post.cz

Bug-Reference-ID: <228.177-19682-1132061412-1179356692@post.cz>

|
|
|
|
Bug-Description:
|
|
|
|
In certain cases, bash can lose the saved status of a background job, though
|
|
it should still be reported by `wait'. Bash can also loop infinitely after
|
|
creating and waiting for 4096 jobs.
