hi 
The couchdb we use which depend on the dynamic library libmozjs185.so. 
When the couchdb running in the environment of arm ubuntu16.04, we go to query the db-view and find that couchjs has crashed. 
We check the coredump file via gdb and find that the stack is in the function js_GetClassPrototype.

(gdb) 
#0  0x0000ffff825fdf60 in js_GetClassPrototype(JSContext*, JSObject*, JSProtoKey, JSObject**, js::Class*) () from /usr/lib/libmozjs185.so.1.0

We are using spidermonkey 1.8.5 on ARM
Can anyone confirm this?
