lldb-3.9 hangs when I try to open a dump from a dotnet application. The process gets completely stuck, without consuming CPU.
$ gdb -v

$ lldb-3.9 -v

$ sudo lldb-3.9 `which dotnet` -c core.27247 -d
(lldb) target create "/usr/bin/dotnet" --core "core.27247"
The prompt never gets to (lldb) ever again. I do not even have the chance to load SOS plugin.
The application is just a infinite loop that prints "Hello world" and sleeps for one second before looping again.
UPDATE
It loads with lldb-3.6, but unfortunately lldb-3.6 has an unrelated bug
