Gurobi crashing on R 3.4

[Matt Strimas-Mackey]

The Gurobi R package has recently started causing my R session to crash. This coincided with a recent update to R 3.4. Running this example:

library("gurobi")
model  <- list()
model$A      <- matrix(c(1, 2, 3, 1, 1, 0), nrow = 2, ncol=3, byrow=T)
model$obj    <- c(1, 1, 2)
model$sense  <- c("<=", ">=")
model$rhs    <- c(4, 1)
model$vtype  <- "B"
params <- list(Presolve=2, TimeLimit=100.0)
result <- gurobi(model, params)

Gives the following error:

 *** caught segfault ***

address 0x128, cause 'memory not mapped'

Traceback:

 1: .C("gurobi_R_solve", as.character(filename), as.integer(rows),     as.integer(cols), as.double(obj), as.integer(modelsense),   ...

 2: grb_solve(filename, rows, cols, obj, modelsense, modelname, objcon,     A_csc$beg, A_csc$ind, A_csc$val, sense, rhs, lb, ub, vtype,   ...

 3: gurobi_common(model, "", params)

 4: gurobi(model, params)

Anyone else experiencing this or have any ideas what's going on? Thanks!

R 3.4 is not currently supported (see http://www.gurobi.com/products/supported-platforms). This will be fixed in the next release.
