Linking my C++ application leads to an ICE. The command invoked is:
x86_64-w64-mingw32-g++ -O3 -s -static -municode -D_UNICODE
-Wl,--allow-multiple-definition -flto -flto-partition=none -fuse-linker-plugin
-Wl,--gc-sections -Llib64 -L../libpcfxx/lib64 -o bin/pp.exe bin/pp.o
bin/posix_main.o bin/pp/Script.o bin/pp/Execution.o bin/pp/Variable.o
bin/pp/Shell.o bin/pp/Database.o bin/pp/Type.o bin/pp/parser/Utility.o
lib64/libpcfxx.a -lpcfxx -lboost_program_options -lboost_locale
-lboost_filesystem -lboost_iostreams -lboost_date_time -lboost_thread
-lboost_regex -lboost_system -lpcf -lsqlite3 -lws2_32
Passing -fno-use-linker-plugin instead of -fuse-linker-plugin works just fine
even if all files were compiled with -flto (flat object file).
Attached you can find the backtrace of the ICE.
