My x11vnc on Fedora has recently started crashing with the following error:
*** stack smashing detected ***:
This issue seems to come and go for a lot of people with x11vnc. Bugs have been reported, but nobody seems to be able to pin it down. One workaround is to recompile it from source with some memory protections disabled, but that is a lot of work .
I found the following workaround to work: launch x11vnc with
-noxrecord on the end. That’s it!
