Truffle compilation problem

[Michael Haupt]

Hi,

in FastR, we're facing the problem shown below. The stack trace doesn't give away a particular location in the FastR sources - we're nevertheless looking at uses of HashMap. Still, it is somewhat odd that the trace ends with an R function (usually we were given traces that ended up somewhere in FastR node classes, which made it much easier to track the issue down).

Best,

Michael
