Issue description

OpenVINO's GPU plugin segfaults every time when compiling a model against an Intel Gen12 iGPU (i5-12500, UHD 770). Device enumeration works fine and correctly reports both CPU and GPU — the crash happens specifically at compile_model(), not before.

Compute runtime packages currently installed in the container, in case it's relevant: intel-igc-core 1.0.17537.24 intel-igc-core-2 2.32.7 intel-igc-opencl 1.0.17537.24 intel-igc-opencl-2 2.32.7 intel-level-zero-gpu-legacy1 1.5.30872.36 intel-opencl-icd 26.14.37833.4-0 intel-opencl-icd-legacy1 24.35.30872.36 level-zero 1.28.2 libze-intel-gpu1 26.14.37833.4-0

I noticed there's no non-legacy intel-level-zero-gpu package, only the legacy one, sitting alongside a much newer opencl-icd. Not sure if that's actually the cause but it seemed worth mentioning since it's the only thing that looked off to me.

Things I ruled out before filing this:

• VAAPI/decode is totally fine on this box, confirmed separately with vainfo (iHD driver 25.2.6, full profile list including H264/HEVC/etc)
• No GPU-related errors in dmesg at all around the crash, so it doesn't look like a kernel-level hang
• Tried both "GPU" and "GPU.0" as the device string, same crash either way
• CPU device compiles and runs the same model without any issue

No Python traceback gets printed, just a hard segfault (Fatal Python error: Segmentation fault, exit 139). Happy to grab any other diagnostics if it'd help track this down.

Step-by-step reproduction

from openvino.runtime import Core core = Core() print(core.available_devices) # prints ['CPU', 'GPU'] just fine model = core.read_model('/openvino-model/ssdlite_mobilenet_v2.xml') compiled = core.compile_model(model, 'GPU') # segfaults here, exit code 139

Issue submission checklist

• I'm reporting an issue. It's not a question.
• I checked the problem with the documentation, FAQ, open issues, Stack Overflow, etc., and have not found a solution.
• There is reproducer code and related data files such as images, videos, models, etc.
