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. Then running make eventually gives libtool: link: /home/abenson/gcc-build/./gcc/xgcc -shared-libgcc -B/home/ abenson/gcc-build/./gcc -nostdinc++ -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 -B/home/abenson/Galacticus/Tools/x86_64-pc-linux-gnu/bin/ -B/ home/abenson/Galacticus/Tools/x86_64-pc-linux-gnu/lib/ -isystem /home/abenson/ Galacticus/Tools/x86_64-pc-linux-gnu/include -isystem /home/abenson/ Galacticus/Tools/x86_64-pc-linux-gnu/sys-include -fno-checking -fPIC -DPIC -D_GLIBCXX_SHARED -shared -nostdlib /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 -Wl,--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 -Wl,--no-whole- archive -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 -lm -L/home/ abenson/gcc-build/./gcc -L/lib/../lib64 -L/usr/lib/../lib64 -lc -lgcc_s /home/ abenson/gcc-build/./gcc/crtendS.o /usr/lib/../lib64/crtn.o -Wl,-O1 -Wl,-z - Wl,relro -Wl,--gc-sections -Wl,--version-script=libstdc++-symbols.ver -Wl,- soname -Wl,libstdc++.so.6 -o .libs/libstdc++.so.6.0.29 collect2: fatal error: ld terminated with signal 11 [Segmentation fault] compilation terminated. make[6]: *** [libstdc++.la] Error 1 make[6]: Leaving directory `/home/abenson/gcc-build/x86_64-pc-linux-gnu/ libstdc++-v3/src' make[5]: *** [all-recursive] Error 1 make[5]: Leaving directory `/home/abenson/gcc-build/x86_64-pc-linux-gnu/ libstdc++-v3/src' make[4]: *** [all-recursive] Error 1 make[4]: Leaving directory `/home/abenson/gcc-build/x86_64-pc-linux-gnu/ libstdc++-v3' make[3]: *** [all] Error 2 make[3]: Leaving directory `/home/abenson/gcc-build/x86_64-pc-linux-gnu/ libstdc++-v3' make[2]: *** [all-stage1-target-libstdc++-v3] Error 2 make[2]: Leaving directory `/home/abenson/gcc-build' make[1]: *** [stage1-bubble] Error 2 make[1]: Leaving directory `/home/abenson/gcc-build' make: *** [all] Error 2 Using "git bisect" shows that the first bad commit causing this problem is: https://gcc.gnu.org/git/? p=gcc.git;a=commit;h=a68412117fa47786bd82ab79b009ec7933aef476 Has any one else found this problem, or know how to work around it?
