[Issue] DEB packaging fails: `dh_dwz/dwz cannot handle DWARF v5 .debug_str_offsets (amdrocm-amdsmi)`

[chiranjeevipattigidi]

Description:

The Debian packaging step fails when dpkg-buildpackage runs dh_dwz, which invokes dwz. dwz errors out because it does not recognize the DWARF v5 debug section .debug_str_offsets.

@nunnikri deb packing failing in Multi-ARch-CI-Asan workflow, can you take a look ?

Issue details:
Building Debian packages from an ASAN-enabled build fails during the dh_dwz debhelper step:
dh_dwz runs the dwz tool over installed binaries to compress and deduplicate DWARF debug sections, reducing debug package size. It fails on .debug_str_offsets — a section that only exists in DWARF 5 format — which the dwz version on the CI runner (0.14–0.15 on Ubuntu 22.04) does not understand. DWARF 5 support requires dwz 0.16+.
2026-05-06T08:21:49.5464863Z dwz: debian/amdrocm-amdsmi7.13/opt/rocm/core-7.13/lib/libamd_smi.so.26.4.0: Unknown debugging section .debug_str_offsets 2026-05-06T08:21:49.5466059Z dwz: debian/amdrocm-amdsmi7.13/opt/rocm/core-7.13/lib/libgoamdsmi_shim64.so.1.0: Unknown debugging section .debug_str_offsets 2026-05-06T08:21:49.5467281Z dwz: debian/amdrocm-amdsmi7.13/opt/rocm/core-7.13/share/amd_smi/amdsmi/libamd_smi.so: Unknown debugging section .debug_str_offsets 2026-05-06T08:21:49.5468488Z dwz: debian/amdrocm-amdsmi7.13/opt/rocm/core-7.13/share/amd_smi/tests/amdsmitst: Unknown debugging section .debug_str_offsets

Why Normal builds pass and not ASAN:

• Normal builds uses RelWithDebInfo. Which is setting -g1 -gz. (cmake/therock_subproject.cmake#L1649-L1652) -g1 reduces the debug info.
• THEROCK_SPLIT_DEBUG_INFO is set (cmake/therock_subproject.cmake). So the .so or binaries in the package doesnt have embedded DWARD sections. Those will be part of build_id/*.debug files
• ASAN build passes -fsanitize=address -fno-omit-frame-pointer -g(cmake/therock_sanitizers.cmake#L39-L40) to compiler. -g causes dwarf5 to emit and since no SPLIT_DEBUG_INFO is set the sections are part of library/binary elf sections.

2 possible Solutions:

• For asan replace -g with -g1 -gdwarf-4 -> This will force using gdarf4 sections which the tool can handle. Pitfall is slightly lesser debuginfo
• Enable disable-dwz in the packaging script for all the packages. This will reduce the compression of debug info packages and ASAN packages. So the ASAN packages can become huge.

I think first solution is safer
