--- Comment #10 from Philippe Blain <levraiphilippeblain at gmail dot com> ---
I recompiled 10.1 with both CFLAGS and CXXFLAGS set to '-O0 -g' and re-ran my
test. I zippped the core dumped and uploaded it to my dropbox since it's too
big to attach https://www.dropbox.com/s/3jo9fogiuas9cyp/core.52896.zip?dl=1

Here is the backtrace:
~~~
