--- Comment #7 from Sebastien Alaiwan <sebastien.alaiwan at gmail.com> ---
It consistently happens at least on 4 different Debian (stretch) PCs: 
- two DELL desktop at my office (16Gb of RAM each)
- one production HP bladeserver (72Gb of RAM)
- my home PC (8Gb of RAM).

I think we can eliminate bad memory.

We first encountered the problem in the bladeserver, with a real program (our
production system). It's a blocking issue to us so we had to find a workaround
(round memory allocations to the next multiple of 64).
In the meantime, I found a way to reproduce this crash with a reduced test case
(the one I posted here).

However, the reduced test case isn't deterministic, and I don't get the crash
at each run (I would say, 1/3 of the times).
