Seg Fault when clearing Map #135
Description
Hi
I have seen intermittent crashes with my clients caused by Seg faults, I have managed to replicate it once locally and got this stack track
Fatal signal 11 (SIGSEGV), code 1 (SEGV_MAPERR), fault addr 0x60 in tid 25467 (com.test), pid 25467 (com.test)

Before drawing a route to the screen I clear the old one and it seems that is where the crash is occuring.
I am currently running
maplibre-navigation-android: 4.0.0
android-sdk: 11.7.1
Any advice on further investigation would be much appreciated
