|
|
This is definitely caused by https://www.gnunet.org/bugs/view.php?id=1868 : session=0x0, plugin_name=0x0, addr=0x0, addrlen=0 Corruption happened in papi = GST_plugins_find (plugin_name); -> added assertion to ensure: plugin_name != NULL |
|
|
added additional checks to ensure session=0x0, plugin_name=0x0, addr=0x0, addrlen=0, force_address=1, does not occur |
