// Test that debug info generated for auto-inserted deallocator is
// correctly attributed.
// This patch scans for the lineno directly from assembly, which may
// differ between different architectures. Because it mainly tests
// FE generated debug info, without losing generality, only x86
// assembly is scanned in this test.
