For the results : yes it reached around the same mem consumption :
always less than 30MB,
starting at 4MB and it looks to be the same start-up consumption as well

Looks like I managed to reproduce your problem:

I didn't do anything special, no idea why I couldn't see that before.
Bah, I remember now. What I did is running the script with bash version
4.3.11, which is the one you're seeing the bug on. Probably I did that
long ago and then forgot to check the result. I'll check how
reproducible this is.
And no idea how to investigate it further :(
Sorry for late answer but I was quite busy lastly (I moved).
Still using the bash version you're refering to, I'm at 80 Mb usage
after 20 days uptime:

Won't paste the output as well here but /proc/..../smaps shows many
segments, whithin which one is using 75 Mb.
(don't know if it's helpful...).
