Re: triggering of ERR trap differs between bash 3.2.39 & 4.0.28

[Amit Dor-Shifer]

Ok. Same here. (4.0.35 is not yet stable on my distro, gentoo, hence I 
quoted results with 4.0.28).

I'm wondering: CHANGES doesn't refer to any bug numbers or anything. 
Isn't bash using some issue-tracking framework?
I suppose this issue falls under:
<quote>
l.  Changed behavior of shell when -e option is in effect to reflect 
consensus
   of Posix shell standardization working group.
</quote>

Thanks,
Amit
