Description
Using a clean debug build with clang (14.0.6) toolchain, `make CONF=debug test TEST="gtest:os_linux.decoder_get_source_info_valid_vm"` fails with

```
assert(false) failed: No address descriptor found containing offset_in_library.
...
# Problematic frame:
# V  [libjvm.so+0xdc496f]  DwarfFile::DebugAranges::find_compilation_unit_offset(unsigned int, unsigned int*)+0x16f
```

gcc (11.2.0) toolchain works fine.
