wayvnc coredump with latest neatvnc commit b5f37d0 #90

Closed ppascher closed 1 year ago

ppascher commented 1 year ago

When connecting to a wayvnc session I get an error ("TLS Handshake failed") and wayvnc creates a coredump. Reverting the latest neatvnc commit ( commit b5f37d0227c42c1f4b7f99741dbb24435ff4f164 ) fixes the issue.

Version:

wayvnc -V
wayvnc: v0.6.2-30-g945f590 (master)
neatvnc: v0.6.0-27-gb5f37d0 (master)
aml: v0.3.0-1-gede4249 (master)
