Thanks for it, unfortunately, I can't reproduce it with: $ g++ -O3 -DNDEBUG -flto -fno-fat-lto-objects -fconcepts -Wall -Wextra -Werror -g -fPIC -fvisibility-inlines-hidden -march=skylake -Wconversion -Wsign-conversion -Wnon-virtual-dtor -Wold-style-cast -Wpedantic -Wuseless-cast -Wdouble-promotion -Wcast-align -Wduplicated-cond -Wlogical-op -Wrestrict -Wnull-dereference -pedantic -std=gnu++17 App.ii Sentry.ii -c $ g++ Sentry.o App.o -shared -flto with: gcc --version gcc (GCC) 9.4.1 20210825 Can you please try reproducing it locally with the 2 pre-processed file. And can you please share the full linker command line (I posted only the lto1 invocation).
