Sigh, these passed manually here, let me check these

[Comment 5 Alfred Wingate 2025-02-27 17:13:51 UTC]

This appears to occur with optimizations levels above -O0.

$ rm -rf build && CC="clang" CXX="clang++" CFLAGS="-O1" CXXFLAGS="-O1" cmake -B build -DTESTS=ON -DCMAKE_BUILD_TYPE=RelWithDebInfo -G Ninja -DGNUSTEP_CONFIG=GNUSTEP_CONFIG-NOTFOUND 1>/dev/null && cmake --build build -j12 1>/dev/null && /home/ask/sources/libobjc2/build/Test/CXXExceptions
Aborted (core dumped)

Success

$ rm -rf build && CC="clang" CXX="clang++" CFLAGS="-O1" CXXFLAGS="-O1" cmake -B build -DTESTS=ON -DCMAKE_BUILD_TYPE=RelWithDebInfo -G Ninja -DGNUSTEP_CONFIG=GNUSTEP_CONFIG-NOTFOUND 1>/dev/null && cmake --build build -j12 1>/dev/null && /home/ask/sources/libobjc2/build/Test/CXXExceptions
