I triggered a build but GitHub has some difficulties to link it to the PR. Should I create a branch on this repo and not my fork? |

) ### Description `import onnxruntime` segfaults during `dlopen` of `onnxruntime_pybind11_state.so` on Linux. This removes the global initializer in `onnxruntime_pybind_state.cc` that eagerly calls `Env::Default()`, and resolves the platform `Env` on first use at its two call sites instead. ### Motivation and Context The module has a namespace-scope dynamic initializer: ```cpp static Env& platform_env = Env::Default(); ``` Since POSIX telemetry landed (#27379), `Env::Default()` constructs `PosixEnv`, whose `PosixTelemetry` member initializes the 1DS SDK in its constructor. That path reads `defaultRuntimeConfig`, a namespace-scope `static ILogConfiguration` defined in the 1DS SDK's `RuntimeConfig_Default.hpp`, which lives in a **different translation unit of the same shared library**. Dynamic initialization order across translation units is unspecified, and the pybind TU's initializer runs first. `Variant::merge_map` therefore iterates a still zero-initialized `std::map`: `_M_node_count == 0`, but `_M_header._M_left` is `nullptr` rather than self-pointing, so `begin() != end()` and the loop dereferences null. Textbook static initialization order fiasco. Backtrace (Release build relinked without `--strip-all` to recover symbols): ``` #0 std::map<..., Variant>::lower_bound stl_map.h:1307 #1 std::map<..., Variant>::operator[] stl_map.h:509 #2 Variant::merge_map VariantType.hpp:508 #3 RuntimeConfig_Default::RuntimeConfig_Default RuntimeConfig_Default.hpp:97 #4 LogManagerImpl::LogManagerImpl LogManagerImpl.cpp:183 #5 LogManagerFactory::Create LogManagerFactory.cpp:36 #6 LogManagerFactory::lease #7 LogManagerFactory::Get LogManagerFactory.hpp:71 #8 LogManagerProvider::Get LogManagerProvider.cpp:16 #9 onnxruntime::PosixTelemetry::Initialize() #10 onnxruntime::PosixTelemetry::PosixTelemetry() #11 onnxruntime::(anonymous namespace)::PosixEnv::PosixEnv() #12 onnxruntime::Env::Default() #13 _GLOBAL__sub_I_onnxruntime_pybind_state.cc #14 call_init elf/dl-init.c:74 ... #21 _dl_open elf/dl-open.c:905 ``` The crash is independent of `LD_LIBRARY_PATH` and `CUDA_VISIBLE_DEVICES` — it happens before any ORT runtime code runs. `libonnxruntime.so` is unaffected because it contains no global initializer that reaches `Env::Default()`, which is why C/C++ and onnxruntime-genai consumers do not see it. Both remaining uses of `platform_env` are inside pybind lambdas that run long after load, so calling `Env::Default()` there is safe. This also removes the now-stale `TODO: we may delay-init this variable` and a pre-existing `#pragma warning(push)` that should have been `pop`. Note for follow-up: `Env::Default()` is now unsafe to call from any dynamic initializer. This was the only such call site in the tree, but hardening `PosixTelemetry` to defer SDK initialization out of its constructor would remove the hazard entirely. ### Tests Verified on a Linux CUDA 13 Release build (`onnxruntime_USE_TELEMETRY` enabled): - `dlopen` of `onnxruntime_pybind11_state.so` succeeds (previously SIGSEGV). - `import onnxruntime` reports the version and `['CUDAExecutionProvider', 'CPUExecutionProvider']`. - `onnxruntime.enable_telemetry_events()` / `disable_telemetry_events()` — the two call sites changed here — work. - CPU and CUDA inference sessions produce correct results. - Reproduced and verified with `LD_LIBRARY_PATH` unset and `CUDA_VISIBLE_DEVICES` empty.
