Re: declare(1) not executing inside source'd script

Hm.  Strange.  I will examine the environment for weirdness regarding BASH_ENV 
or anything else that might be an issue.  Given that it happens for me in both 
the stock bash 4.2.46 and the locally built 4.4 (on CentOS 7.4), there must be 
something common to both and thus external to the shell itself.

I have installed bashdb on this system as well, but I don’t expect that to have 
affected anything since it’s an add on that Bash shouldn’t have noticed without 
the use of --debugger.

Thanks for your help.

PS:  So the official line is to not specify the man section for builtins to the 
shell?  I will not use section numbers in the future. :)
