Chas Emerick commented on COUCHDB-577:
--------------------------------------

A fellow in Mozilla irc (thanks evilpie!) helped me determine the version of spidermonkey in use from the binary, using {{strings libmozjs.dylib | grep "JavaScript-C"}}. The result for my Couchbase Single install that exhibits this problem was:

{{JavaScript-C 1.8.0 pre-release 1 2007-10-03}}

The reaction to that was that "this version is really old". :-)

I haven't been following the relevant discussions too closely, but it sounds like upgrading spidermonkey 1.8.5 is a breaking change that is waiting on some newer version of couchdb(?).  In any case, it seems like a dependency upgrade is the only way forward, i.e. it doesn't sound like there are any simple options to twiddle.
