Thanks for pointing that out. It seems that the actual linker command that's segfaulting is: /usr/bin/ld -v --eh-frame-hdr -m elf_x86_64 -shared -o .libs/libstdc++.so. 6.0.29 -L/home/abenson/gcc-build/x86_64-pc-linux-gnu/libstdc++-v3/src -L/home/ abenson/gcc-build/x86_64-pc-linux-gnu/libstdc++-v3/src/.libs -L/home/abenson/ gcc-build/x86_64-pc-linux-gnu/libstdc++-v3/libsupc++/.libs -L/home/abenson/ gcc-build/x86_64-pc-linux-gnu/libstdc++-v3/libsupc++/.libs -L/home/abenson/ gcc-build/x86_64-pc-linux-gnu/libstdc++-v3/src -L/home/abenson/gcc-build/ x86_64-pc-linux-gnu/libstdc++-v3/src/.libs -L/home/abenson/gcc-build/./gcc -L/ lib/../lib64 -L/usr/lib/../lib64 -L/home/abenson/gcc-build/./gcc -L/lib/../ lib64 -L/usr/lib/../lib64 /usr/lib/../lib64/crti.o /home/abenson/gcc-build/./ gcc/crtbeginS.o .libs/compatibility.o .libs/compatibility-debug_list.o .libs/ compatibility-debug_list-2.o .libs/compatibility-c++0x.o .libs/compatibility- atomic-c++0x.o .libs/compatibility-thread-c++0x.o .libs/compatibility-chrono.o .libs/compatibility-condvar.o --whole-archive ../libsupc++/.libs/libsupc+ +convenience.a ../src/c++98/.libs/libc++98convenience.a ../src/c++11/.libs/ libc++11convenience.a ../src/c++17/.libs/libc++17convenience.a ../src/c+ +20/.libs/libc++20convenience.a --no-whole-archive -lm -lc -lgcc_s /home/ abenson/gcc-build/./gcc/crtendS.o /usr/lib/../lib64/crtn.o -O1 -z relro --gc- sections --version-script=libstdc++-symbols.ver -soname libstdc++.so.6GNU ld version 2.20.51.0.2-5.42.el6 20100205 On Wednesday, September 22, 2021 2:37:27 PM PDT Jeff Law wrote: > On 9/22/2021 2:25 PM, Andrew Benson via Gcc-help wrote: > > I'm attempting to build GCC (current git master) but am running into a > > segfault. > > > > I'm configuring using: > > > > ./gcc-git/configure --prefix=/home/abenson--enable-languages=c,c++,fortran > > -- disable-multilib > > > > which appears to succeed.
