Describe the bug using graftcp with some tools stalls indefinitely

To Reproduce Steps to reproduce the behavior: graftcp-local -socks5 :9050 graftcp curl ipinfo.io

Expected behavior contrary to curl, wget doesn't stall and works

Desktop (please complete the following information):

@untoreh I can't reproduce it on my machine for the moment, maybe I should build a virtual machine of alpine linux 3.8. Thank you for the feedback.

Sorry to necrobump this, but I'm having the same issue with wine 7.0 (most likely affects any version).

Merely running wine cmd with graftcp causes the following, ad infinitum:
