Description
I'm trying to compile OpenCV and OpenCV_contrib on Windows using clang-cl version 19.1.7. Both Debug and Release modes encounter errors. Here are the CMake commands I used for each mode:
Debug modecmake -S . -B build-clang-cl -G Ninja -DCMAKE_C_COMPILER=clang-cl -DCMAKE_CXX_COMPILER=clang-cl -DCMAKE_BUILD_TYPE=Debug -DCMAKE_C_FLAGS="-g -mssse3 -msse4.1" -DCMAKE_CXX_FLAGS="-g -mssse3 -msse4.1" -DBUILD_opencv_world=true -DOPENCV_EXTRA_MODULES_PATH=E:\31864\Downloads\Compresse\opencv_contrib-4.11.0\modulesRelease modecmake -S . -B build-clang-cl -G Ninja -DCMAKE_C_COMPILER=clang-cl -DCMAKE_CXX_COMPILER=clang-cl -DCMAKE_BUILD_TYPE=Release -DCMAKE_C_FLAGS="-O2 -DNDEBUG -mssse3 -msse4.1" -DCMAKE_CXX_FLAGS="-O2 -DNDEBUG -mssse3 -msse4.1" -DBUILD_opencv_world=true -DOPENCV_EXTRA_MODULES_PATH=E:\31864\Downloads\Compresse\opencv_contrib-4.11.0\modulesHowever, both commands result in errors. Strangely, using Seeing the message "PLEASE submit a bug report to https://github.com/llvm/llvm-project/issues/ and include the crash backtrace, preprocessed source, and associated run script.", I've decided to submit this report. I'm a newbie in the field of computers, so please forgive me if I cause any inconvenience.

I think this is a duplication of #109576. The reason is FE doesn't generate a closed seh.scope: https://godbolt.org/z/86dr4vPjz I don't know what happens on FE since I'm not expertised on it. Hope the fix of #93251 may inspire a solution. |

However, both commands result in errors. Strangely, using
clangto compile in both Debug and Release modes works fine without any issues.Seeing the message "PLEASE submit a bug report to https://github.com/llvm/llvm-project/issues/ and include the crash backtrace, preprocessed source, and associated run script.", I've decided to submit this report.
