Loading plugin causes crash #59

Open dkfulp opened 5 years ago

dkfulp commented 5 years ago

I can load my plugin fine a few times, but when I unload the plugin and then reload it a couple of times, decaf seg faults.

The full process goes:

  1. load_plugin A
  2. .... use plugin ....
  3. unload_plugin
  4. Go back to step 1 and repeat

Any ideas why it is seg_faulting?

There might be a bug that a callback created by the plugin is not removed properly when the plugin is unloaded. A gdb backtrace would help.
