Segfault with CxxWrap on Raspberry Pi

Hi,

I experiencing a segfault when trying to use the hello demo with CxxWrap.
I am using julia 1.4 and CxxWrap 0.10.0 (and libcxxwrap_julia_jll 0.7 installed by CxxWrap) on a Raspberry Pi (armv7l) with raspbian buster

When I load the library in julia I have the following output

The same example works fine on x86_64 linux.
Has anybody experienced the same ? I could definitely use some help
