Bug Description
(GNU bash 4.3.46)
(ubuntu 16.04 LTS)
Consider you have out.txt on current dir.
-------
>exec 123456789012>
bash: exec: 123456789012: not found
-------
exec command prints indicated error for large numbers that is supposed to use as a fd but redirects /proc/$$/fd/1 to out.txt silently.
Additionally,
-------
>exec 1234567890>out.txt
bash: 123456789: Bad file descriptor
-------
For large numbers but not that large (I don't inspect the limits!), exec command rejects fd number but silently adds a new fd to current bash process. In every execution of the command, bash adds a new fd to itself again and again.
