Summary: Pull Request resolved: https://github.com/pytorch/pytorch/pull/78297 Clone followed by expand/expand_as due to memoryOverlap check on copy_ native method. Refer to T118519310 for more details. Crashing test case: a = tensor(3,1) // strides = (1,1) B = tensor(3,2) // strides = (2,1) Temp = a.expand_as(b). // creates temp with shape as (3,2) and strides as (1,0) temp.clone() // crashe on copy_ due to memoryOverlap Fix: Disable the out variant for the expanded tensor. - Calls native clone instead of out variant for clone dealing with expanded tensors - Added test case for both clone variants (out and native clones) - Increased the tensor size for memory planner test case to trigger dynamic allocation Test Plan: buck test caffe2/benchmarks/static_runtime/fb:test_fb_operators buck test caffe2/benchmarks/static_runtime:static_runtime_cpptest Differential Revision: D36672180 Pull Request resolved: https://github.com/pytorch/pytorch/pull/78322 Approved by: https://github.com/mikeiovine
