            Bug ID: 46453
           Summary: [WebAssembly] [DWARF] error: DIE has overlapping
                    ranges
           Product: libraries
           Version: trunk
          Hardware: PC
                OS: Linux
            Status: NEW
          Severity: enhancement
          Priority: P
         Component: Backend: WebAssembly
          Assignee: unassignedbugs at nondot.org
          Reporter: alonzakai at gmail.com
                CC: llvm-bugs at lists.llvm.org

STR: in emscripten,

EMMAKEN_CFLAGS="-g -w" EMCC_DEBUG=1 ./tests/runner.py  wasm2.test_zlib_cmake

llvm-dwarfdump --verify /tmp/emscripten_temp/emcc-0-base.wasm

That prints

error: DIE has overlapping ranges in DW_AT_ranges attribute:
[0x0000000000000006, 0x0000000000000132) and [0x0000000000000000,
0x0000000000000385)
error: DIE has overlapping ranges in DW_AT_ranges attribute:
[0x0000000000000000, 0x0000000000000385) and [0x0000000000000134,
0x00000000000002d8)
error: DIE has overlapping ranges in DW_AT_ranges attribute:
[0x0000000000000000, 0x0000000000000385) and [0x00000000000002da,
0x0000000000000487)

This may be the same as https://bugs.llvm.org/show_bug.cgi?id=18790 , I'm not
sure.
