Broken CURL operations

[Carsten Schlote]

The official dub package fails to operate properly with libcurl. It aborts with unexpected error in runtime.

However, a dub version compiled with ldc2 (also compiled from sources) works fine:

The problem prevents the use of all packages on code.dlang.org as it aborts with 'https://code-mirror.dlang.io/, registry at https://dub-registry.herokuapp.com/): HTTP request returned status code 0 ()'.

Same problem here, I submitted a diff bug report, but this was what I was getting at. It's interesting because it doesn't appear on this version in other distros.

[Carsten Schlote (carsten-schlote)]

The problem seems to be related to broken HTTP/2 status line support in libphobos. There is some patch available, which hopefully will appear in the GDC package soon. This should fix all packages using GDC for compilation.

Status changed to 'Confirmed' because the bug affects multiple users.

Works for me as of latest version. :)
