           Summary: std.net.curl: misbehaviour on arch 'arm32v7 gnueabihf'
                    (Raspberry/Raspbian/Buster)
           Product: D
           Version: D2
          Hardware: Other
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P1
         Component: phobos
          Assignee: nobody at puremagic.com
          Reporter: schlote at vahanus.net

Tried to do this:
'''
import std.net.curl;
import std.stdio;

void main()
{
    auto data = get("https://acme-staging-v02.api.letsencrypt.org/directory");
    writeln(data);
}
'''
Works fine on intel, but crashes on Raspberry:
