Fixes #1864.
When the
local_sizeof aLRNLayerinACROSS_CHANNELSmode is larger than the number of channels in a blob, we get some nasty indexing errors in the GPU implementation (the CPU implementation is fine). This pull request consists of two contributions:TestForwardAcrossChannelsLargeRegionandTestGradientAcrossChannelsLargeRegionthat use alocal_sizeof 15 on a blob with 7 channels. These tests break the current master implementation.As far as I can tell, this PR is complete, though if anyone finds anything wrong with it of course I'd be happy to fix.
