--- Comment #4 from Steve Kargl <kargl at gcc dot gnu.org> --- (In reply to Lorenzo Salvadore from comment #3) > I see the bug in FreeBSD versions 14.3-RELEASE, 15.0-RELEASE and > 16.0-CURRENT (16.0-CURRENT #2 main-n282366-8291ea8761c2: Sun Dec 14 14:18:53 > CET 2025). I have not tested other versions. > > These are our configure arguments: > > configure --without-isl --enable-multilib > --with-build-config=bootstrap-debug --disable-nls --disable-libssp > --enable-gnu-indirect-function --enable-host-shared --enable-plugin > --libdir=/usr/local/lib/gcc16 --libexecdir=/usr/local/libexec/gcc16 > --program-suffix=16 --with-as=/usr/local/bin/as --with-gmp=/usr/local > --with-gxx-include-dir=/usr/local/lib/gcc16/include/c++/ > --with-gxx-libcxx-include-dir=/usr/include/c++/v1 > --with-ld=/usr/local/bin/ld --with-pkgversion=FreeBSD Ports Collection > --with-system-zlib --without-zstd --enable-languages=c,c++,objc,fortran,jit > --prefix=/usr/local --localstatedir=/var --mandir=/usr/local/share/man > --infodir=/usr/local/share/info/gcc16 --build=x86_64-portbld-freebsd15.0 I just bootstrapped top-of-tree gcc with the above configure command line where I needed to remove --build=x86_64-portbld-freebsd15.0 and --with-pkgversion=FreeBSD Ports Collection. The initial compiler in the bootstrap process was FreeBSD's clang system compiler. I do not see the failure you are reporting. However, I then remembered that the FreeBSD port has several patches that have not been upstreamed. % ls /usr/ports/lang/gcc16-devel/files patch-arm-unwind-cxx-support patch-gcc_Makefile.in patch-gcc_configure patch-gcc_jit_Make-lang.in patch-gcc_jit_jit-recording.cc patch-gcc_jit_libgccjit.cc patch-gfortran-libgcc patch-libcxxrt patch-libgcc_unwind-dw2-fde-dip.c patch-libgcc_unwind.inc patch-libsanitizer_asan_asan__linux.cpp patch-libsanitizer_asan_asan__thread.cpp pkg-message.in Of these patches, it seems that patch-libcxxrt may be worth investigating.
