| ## Test that llvm-dwarfdump --verify correctly handles DW_TAG_call_site |
| ## nested inside a DW_TAG_lexical_block. Previously, the parent-walking |
| ## loop in verifyDebugInfoCallSite() used Die.getParent() instead of |
| ## Curr.getParent(), causing an infinite loop when the call_site's |
| ## immediate parent was not a subprogram (e.g., a lexical_block). |

| # RUN: yaml2obj %s -o - | llvm-dwarfdump --verify - 2>&1 | FileCheck %s |
| |
| # CHECK: No errors. |
