Package: src:mapbox-variant Version: 1.2.0-3 Severity: serious Tags: ftbfs forky sid
Dear maintainer: During a rebuild of all packages in unstable, your package failed to build. Below you will find how the build ends (probably the most relevant part, but not necessarily). If required, the full build log is available here: https://people.debian.org/~sanvila/build-logs/202509/ About the archive rebuild: The build was made on virtual machines from AWS, using sbuild and a reduced chroot with only build-essential packages. If you could not reproduce the bug please contact me privately, as I am willing to provide ssh access to a virtual machine where the bug is fully reproducible. If this is really a bug in one of the build-depends, please use reassign and add an affects on src:mapbox-variant, so that this is still visible in the BTS web page for this package. Thanks. -------------------------------------------------------------------------------- [...] debian/rules clean dh clean dh_auto_clean make -j2 clean make[1]: Entering directory '/<<PKGBUILDDIR>>' rm -rf ./out rm -rf *.dSYM rm -f unit.gc* rm -f *gcov rm -f test/unit.gc* rm -f test/*gcov rm -f *.gcda *.gcno make[1]: Leaving directory '/<<PKGBUILDDIR>>' dh_clean debian/rules binary dh binary dh_update_autotools_config dh_autoreconf dh_auto_configure dh_auto_build make -j2 "INSTALL=install --strip-program=true" make[1]: Entering directory '/<<PKGBUILDDIR>>' mkdir -p ./out mkdir -p ./out g++ -o out/bench-variant test/bench_variant.cpp -I./include -isystem test/include -std=c++11 -Werror -Wall -Wextra -pedantic -Wformat=2 -Wsign-conversion -Wshadow -Wunused-parameter -O3 -DNDEBUG -march=native -DSINGLE_THREADED -fvisibility-inlines-hidden -fvisibility=hidden -g -O2 -ffile-prefix-map=/<<PKGBUILDDIR>>=. -fstack-protector-strong -fstack-clash-protection -Wformat -Werror=format-security -fcf-protection -pthread -Wl,-z,relro g++ -o out/unique_ptr_test test/unique_ptr_test.cpp -I./include -isystem test/include -std=c++11 -Werror -Wall -Wextra -pedantic -Wformat=2 -Wsign-conversion -Wshadow -Wunused-parameter -O3 -DNDEBUG -march=native -DSINGLE_THREADED -fvisibility-inlines-hidden -fvisibility=hidden -g -O2 -ffile-prefix-map=/<<PKGBUILDDIR>>=. -fstack-protector-strong -fstack-clash-protection -Wformat -Werror=format-security -fcf-protection -pthread -Wl,-z,relro mkdir -p ./out g++ -o out/recursive_wrapper_test test/recursive_wrapper_test.cpp -I./include -isystem test/include -std=c++11 -Werror -Wall -Wextra -pedantic -Wformat=2 -Wsign-conversion -Wshadow -Wunused-parameter -O3 -DNDEBUG -march=native -DSINGLE_THREADED -fvisibility-inlines-hidden -fvisibility=hidden -g -O2 -ffile-prefix-map=/<<PKGBUILDDIR>>=. -fstack-protector-strong -fstack-clash-protection -Wformat -Werror=format-security -fcf-protection -pthread -Wl,-z,relro In file included from /usr/include/c++/15/ios:44, from /usr/include/c++/15/bits/ostream.h:43, from /usr/include/c++/15/ostream:42, from /usr/include/c++/15/iostream:43, from test/bench_variant.cpp:3: In static member function âstatic void std::char_traits<char>::assign(char_type&, const char_type&)â, inlined from âstatic void std::__cxx11::basic_string<_CharT, _Traits, _Alloc>::_S_copy(_CharT*, const _CharT*, size_type) [with _CharT = char;
