Not working with big data

[AlikiZ]

Thanks for such a fast package. I am using the python pycasso on a subset of big data for design matrix X. It works for X with dimensions 210,000 x 123,916 , but it fails with Segmentation fault for X with dimensions 235,495 x 123,916 (X is always a subset of the same data). Debugging with gdb shows

In the python the error is thrown in pycasso/core.py, line 209 in wrapper.
What do you suggest?
