The following code causes the script to crash for no reason:
key getKey( ) {
return NULL_KEY;
}
default {
state_entry() {
llMessageLinked( LINK_SET, 18, "", "" );
}
link_message( integer sender_num, integer channel, string message, key id ) {
key newKey;
newKey = getKey( );
}
}
Error output:

This error is mono-specific - and does not happen with the LSL interpreter.

Functions that return keys cause System.InvalidProgramException
key returnakey() {
return NULL_KEY;
}
default {
state_entry() { key t = returnakey(); }
}

It doesn't happen when the returned key is simply discarded, or when the key is returned directly from a system function (e.g. llGetKey).
