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

```julia

```

The same example works fine on x86\_64 linux.  
Has anybody experienced the same ? I could definitely use some help
