I reproduced the bug on Fedora 32 with gcc-10.2.1-6.fc32.x86_64 (new) but I failed to reproduce with gcc-10.2.1-1.fc32.x86_64 (old, before I upgraded GCC). So it's a regression of gcc-10.2.1-6.fc32.x86_64 package. The package contains multiple downstream patches: https://src.fedoraproject.org/rpms/gcc/tree/f32 Commands used to reproduce the issue: export MAKEFLAGS=-j10 ./configure --with-lto make Extract of my Makefile: OPT= -DNDEBUG -g -fwrapv -O3 -Wall BASECFLAGS= -Wno-unused-result -Wsign-compare CONFIGURE_CFLAGS_NODIST= -flto -fuse-linker-plugin -ffat-lto-objects -flto-partition=none -g -std=c99 -Wextra -Wno-unused-result -Wno-unused-parameter -Wno-missing-field-initializers -Werror=implicit-function-declaration -fvisibility=hidden CONFIGURE_LDFLAGS_NODIST= -flto -fuse-linker-plugin -ffat-lto-objects -flto-partition=none -g ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue42164> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
