Created attachment 894083 [details] build.log and emerge --info I am almost positive this is due to sys-devel/gcc[-ieee-long-double] (does not reproduce on ppc64le 23.0 profiles) so marking it as that rather than as a big-endian problem. gcc.compile.c++ bin.v2/libs/charconv/build/gcc-13.2/gentoorelease/pch-off/threading-multi/visibility-hidden/from_chars.o "powerpc64-unknown-linux-gnu-g++" -fvisibility-inlines-hidden -D_FILE_OFFSET_BITS=64 -D_LARGEFILE_SOURCE -D_LARGEFILE64_SOURCE -O2 -pipe -std=c++17 -fPIC -m64 -pthread -finline-functions -Wno-inline -Wall -fvisibility=hidden -DBOOST_ALL_NO_LIB=1 -DBOOST_CHARCONV_DYN_LINK=1 -DBOOST_CHARCONV_SOURCE=1 -DBOOST_COBALT_USE_STD_PMR=1 -DNDEBUG -I"." -c -o "bin.v2/libs/charconv/build/gcc-13.2/gentoorelease/pch-off/threading-multi/visibility-hidden/from_chars.o" "libs/charconv/build/../src/from_chars.cpp" libs/charconv/build/../src/from_chars.cpp: In function ‘boost::charconv::from_chars_result boost::charconv::from_chars_erange(const char*, const char*, long double&, chars_format)’: libs/charconv/build/../src/from_chars.cpp:258:48: error: ‘compute_float80’ is not a member of ‘boost::charconv::detail’; did you mean ‘compute_float64’? 258 | auto return_val = boost::charconv::detail::compute_float80<long double>(exponent, significand, sign, success); | ^~~~~~~~~~~~~~~ | compute_float64 libs/charconv/build/../src/from_chars.cpp:258:64: error: expected primary-expression before ‘long’ 258 | auto return_val = boost::charconv::detail::compute_float80<long double>(exponent, significand, sign, success); | ^~~~
OK, removing this from the title, this selectively fails on ppc64le sometimes, but only with very high optimization flags. It always fails on ppc64 BE.
