Fetching the patches during the build is taking a lot of time, if - as in my case - the name resolution of ftp.gnu.org takes literally minutes with $XBPS_FETCH_CMD. If more patches for bash 4.3 are created, just add them to srcpkgs/bash/files and adjust _bash_patchlevel accordingly.

Bug-Description:
|
|
|
|
Bash does not clean up the terminal state in all cases where bash or
|
|
readline modifies it and bash is subsequently terminated by a fatal signal.
|
|
This happens when the `read' builtin modifies the terminal settings, both
|
|
when readline is active and when it is not. It occurs most often when a script
|
|
installs a trap that exits on a signal without re-sending the signal to itself.
|
|
|
|
