OpenMx Does Not Provide Correct Results for Example Code?

I'm using the latest version of OpenMx on Ubuntu 16.04. I re-installed it a few minutes ago hoping it would fix what appears to be wrong. I'm also running OpenMx on Ubuntu 15.04 on another computer which appears to work correctly.

Here is the example code from mxTryHard:

library(OpenMx)

data(demoOneFactor) # load the demoOneFactor dataframe

manifests <- names(demoOneFactor) # set the manifest to the 5 demo variables
latents <- c("G") # define 1 latent variable
model <- mxModel(model="One Factor", type="RAM",
manifestVars = manifests,
latentVars = latents,
mxPath(from=latents, to=manifests, labels=paste("b", 1:5, sep="")),
mxPath(from=manifests, arrows=2, labels=paste("u", 1:5, sep="")),
mxPath(from=latents , arrows=2, free=FALSE, values=1.0),
mxData(cov(demoOneFactor), type="cov", numObs=500)
)
model <- mxTryHard(model) # Run the model, returning the result into model
summary(model) # Show summary of the fitted model

Here are the results:

> model <- mxTryHard(model) # Run the model, returning the result into model

I tried this several times with the same results.

Now I just ran it again in the same session and I get what I think are the correct results.

The problem is, when I run my real model under 15.04 on the other computer, I get entirely reasonable results with confidence intervals. When I run it under 16.04 on this computer, all I get are error messages or if I ask for confidence intervals the code runs but never appears to finish.

The problem with 16.04 has been going on for months so I had switched to the other computer. I tried again by re-installing or installing the latest version on the 16.04 computer but OpenMx still seems to be broken under 16.04.
