DUB :

Any idea of what is happening here ?

It's not an old beta, it's a version slightly newer than dub 
v1.20 (with an LDC-specific convenience fix), see 
https://github.com/ldc-developers/ldc/commit/6847b4c1fca2a9897117604b4e17058a55ad616c#diff-1e414d8d7f312
536ae878fbfe29f036. In dub master at the time, the version file contained
v1.20.0-beta.2, while it was actually post-1.20.

If your issue is fixed today, then it was related to 
https://github.com/dlang/dub/issues/1928 and solved via 
code.dlang.org changed from http/2 to http/1.1. (Workaround for a 
curl bug in phobos).

Kind regards
Andre

Keeps happening...
But If I understand correctly, it's a problem of LDC+DUB, not 
from the code... It' compiles&run correctly on Linux with DMD and 
LDC, and on Windows with DMD and LDC 64 bit (same version)

I can reproduce a segfault (reading from null) in libcurl.dll 
used by dub, with the 32-bit Windows release. As libcurl was 
upgraded with LDC v1.21, I also tried the older one bundled with 
LDC v1.20, same segfault. I've then tried the older dub (v1.19) 
bundled with LDC v1.20, same segfault.
