JS embedded engine crashes on initialization

I'm trying to embed spidermonkey engine (60.1.1pre3) into a c++ app that is statically built with libjs_static.a. The app itself is juts an empty main. JS engine crashes (SIGSEGV) when it initializes a static variable in WasmBuitins.cpp

Mutex initBuiltinThunks(mutexid::WasmInitBuiltinThunks);

Is there anything that has to be done to link spider monkey library correctly?
