Re: Race in bash-4.3 'typeset'?

Ah! You're right. The second issue was already reported back in 2015
https://lists.gnu.org/archive/html/bug-bash/2015-02/msg00060.html

Now, regarding the SIGPIPE issue. The message bash is printing just
means that grep closed the pipe, so the bash process receives a
SIGPIPE when attempting to write. The output of strace (make sure you
use -f to follow forks) will make things easier to find out where the
issue is.
