This is because the test is expecting the following error message when this test fails:
"dereference of modified alloc_mem ptr R1"
But we are using "helper wants pointer to allocated memory" from SAUCE patch 33623ca13a "UBUNTU: SAUCE: bpf: prevent helper argument PTR_TO_ALLOC_MEM to have offset other than 0" (bug 1956585)
