BASH PATCH REPORT
|
||||
=================
|
||||
|
||||
Bash-Release: 5.0
|
||||
Patch-ID: bash50-017
|
||||
|
||||
Bug-Reported-by: Valentin Lab <valentin.lab@kalysto.org>
|
||||
Bug-Reference-ID: <ab981b9c-60a5-46d0-b7e6-a6d88b80df50@kalysto.org>

Bug-Reference-URL: https://lists.gnu.org/archive/html/bug-bash/2020-03/msg00062.html
|
||||
|
||||
Bug-Description:
|
||||
|
||||
There were cases where patch 16 reaped process substitution file descriptors
|
||||
(or FIFOs) and processes to early. This is a better fix for the problem that
|
||||
bash50-016 attempted to solve.
|
||||
|
||||
Patch (apply with `patch -p0'):
