Tom, what target did you reproduce on? I'm able to reproduce this on Fedora 23 using -fno-use-linker-plugin: $ /ssd/uros/gcc-build/gcc/xgcc -B /ssd/uros/gcc-build/gcc -O2 -flto -fno-use-linker-plugin -c attr-weakref-1_0.c $ /ssd/uros/gcc-build/gcc/xgcc -B /ssd/uros/gcc-build/gcc -O2 -flto -fno-use-linker-plugin -c attr-weakref-1_1.c $ /ssd/uros/gcc-build/gcc/xgcc -B /ssd/uros/gcc-build/gcc -O2 -flto -fno-use-linker-plugin -c attr-weakref-1_2.c $ /ssd/uros/gcc-build/gcc/xgcc -B /ssd/uros/gcc-build/gcc -O2 -flto -fno-use-linker-plugin attr-weakref-1_0.o attr-weakref-1_1.o attr-weakref-1_2.o /tmp/ccydxp6I.s: Assembler messages: /tmp/ccydxp6I.s: Error: symbol definition loop encountered at `callmealias.lto_priv.1' /tmp/ccydxp6I.s: Error: symbol definition loop encountered at `callmealias.lto_priv.0' lto-wrapper: fatal error: /ssd/uros/gcc-build/gcc/xgcc returned 1 exit status compilation terminated. collect2: fatal error: lto-wrapper returned 1 exit status compilation terminated. (The compilation works OK w/o -fno-use-linker-plugin.)
