The full one is cc1plus -fpreprocessed qv4qobjectwrapper.cpp.ii -mptr64 -mstack-bias -mno-v8plus -quiet -m64 -mcpu=v9 -g -O2 -std=c++17 -version -flto=auto -ffat-lto-objects -fstack-protector-strong -fPIC -fvisibility=hidden -fvisibility-inlines-hidden -fno-exceptions -o qv4qobjectwrapper.cpp.s With the original testcase and cc1plus from the gcc-13 branch, this can be reduced to cc1plus -fpreprocessed qv4qobjectwrapper.cpp.ii -mptr64 -mstack-bias -mno-v8plus -quiet -m64 -mcpu=v9 -O2 -fno-exceptions -o qv4qobjectwrapper.cpp.s while without -fno-exceptions the test compiles in this configuration. Fortunately, I managed to reduce the testcase as attached, which SEGVs even without -fno-exceptions. On trunk, the original testcase compiles without issues, while the reduced one SEGVs since gcc-8 (didn't try before) up to trunk.
