When running
`/opt/rocm/llvm/bin/llvm-objdump -D temp.o`, I see:
```
PLEASE submit a bug report to https://github.com/llvm/llvm-project/issues/ and include the crash backtrace.
Stack dump:
0. Program arguments: /opt/rocm/llvm/bin/llvm-objdump -D temp.o
Segmentation fault (core dumped)
```
The backtrace is below. Let me know if you need the temp.o file (250 MB)
```
