You should compile with -d3 flag so we can get more details such as functions that are shown as ?? and lines: https://github.com/Zeex/samp-plugin-...ith-debug-info
Also if you don't use 4.15.1 crashdetect version, update it: https://github.com/Zeex/samp-plugin-...etect/releases

Re-run the server and if you get information with [debug] prefix in server log, post them here.
