SIGSEGV libosrm with node12 #5841
Description
Hey! I am receiving segfault when using libosrm 5.22 with node12 bindings. The service crashes when we are using route method and in the same time we are loading new dataset into shared memory with osrm-datastore. Crashes are happening when using exclude parameter from route method, otherwise seems to work fine. I couldn't reproduce the problem on localhost, so I don't have a dataset that could help debugging this. The node process runs in docker container with --ipc=host.
I also have a stack trace:
