Can you be more specific about

• osrm-backend version
• compiler and stdlib version
• lua and luabind version
• ldd libluabind.so to see which lua version luabind was linked against
• the cmake output

This looks related to: https://github.com/Project-OSRM/osrm-backend/issues/2590.

The function is defined here: https://github.com/Project-OSRM/osrm-backend/blob/master/include/extractor/extraction_helper_functions.hpp#L105-L108

And exported here: https://github.com/Project-OSRM/osrm-backend/blob/master/src/extractor/scripting_environment.cpp#L80

It seems that the match between std::int32_t and int might fail in your case. If you are on an older LUA version, try following the information in https://github.com/Project-OSRM/osrm-backend/issues/2590#issuecomment-228712892.

It seems that, for some reason, your system generates a nil value for empty strings. So the issue seems luabind dependent. You can try using https://github.com/Project-OSRM/osrm-backend/pull/2598. This should fix your issues.

Fixed by https://github.com/Project-OSRM/osrm-backend/pull/2598. Waiting for merge.
