R CMD check error on matrix initialization

[nfultz]

I'm doing some benchmarking on our new cluster, got a few test failures on R CMD check on vclMatrix initialization. 00check.log is attached.

Interesting, I'm not sure what is exactly happening. Could you try doing any of those tests directly to see more details of an exact error?

Able to reproduce on one test - https://github.com/cdeterman/gpuR/blob/master/tests/testthat/test_gpuMatrix_algebra.R#L503

It crashes when run through testthat but not when run line-by-line in the console. here is the error message testthat prints:

gpuMatrix algebraR: /home/nfultz/R/x86_64-redhat-linux-gnu-library/3.6/RViennaCL/include/viennacl/ocl/kernel.hpp:232: void viennacl::ocl::kernel::arg(unsigned int, const VCL_TYPE&) [with VCL_TYPE = viennacl::matrix_range<viennacl::matrix<int, viennacl::row_major, 1> >]: Assertion `&val.handle().opencl_handle().context() == &handle_.context() && bool("Kernel and memory object not in the same context!")' failed.
