caught segfault, cause 'memory not mapped'

[zaburo-ch]

I installed this package on OSX 10.11.2 using devtools. Then I ran the below command and caught segfault.

> library(largeVis)
> dat <- as.data.frame(matrix(runif(100*100), 100, 100))
> coords <- vis(dat, check = FALSE, n_tree = 50, tree_th = 700, K = 50, alpha = 1, max.iter = 4)
Searching for neighbors.

 *** caught segfault ***
address 0xfffffffffffffff8, cause 'memory not mapped'

Traceback:
 1: .Call("largeVis_searchTrees", PACKAGE = "largeVis", threshold,     n_trees, K, max_recursion_degree, maxIter, data, verbose)
 2: searchTrees(threshold = tree_threshold, n_trees = n_trees, K = K,     max_recursion_degree = max_depth, maxIter = max_iter, data = x,     verbose = verbose)
 3: randomProjectionTreeSearch(x, n_trees = n_trees, tree_threshold = tree_threshold,     K = K, max_iter = max_iter, max_depth = max_depth, verbose = verbose)
 4: vis(dat, check = FALSE, n_tree = 50, tree_th = 700, K = 50, alpha = 1,     max.iter = 4)

Rcpp used g++ (Homebrew gcc 5.3.0). I also tried using gcc 4.9.2, but same error occurred.

Try the version in the 'bench' branch on here.

The other thing to try, is to try installing with openmp disabled. (The error you're seeing relates to multi-threading.) Let me know if you want to try that and need to be talked through it.

Thanks for replying. I misunderstood that we should pass data as dataframe. It was resolved by using matrix simply.

library(largeVis)
dat <- matrix(runif(100*100), 100, 100)
coords <- vis(dat)

Huh. Ok I'm going to close this. If its not working, then please reopen.
