Any hints? No idea for details but when running lto.exp I see Executing on host: /home/abuild/rguenther/trunk2-g/gcc/xgcc -B/home/abuild/rguenther/trunk2-g/gcc/ -fno-diagnostics-show-caret -fdiagnostics-color=never -flto -c -o lto19653.o lto19653.c (timeout = 300) spawn /home/abuild/rguenther/trunk2-g/gcc/xgcc -B/home/abuild/rguenther/trunk2-g/gcc/ -fno-diagnostics-show-caret -fdiagnostics-color=never -flto -c -o lto19653.o lto19653.c^M Executing on host: /home/abuild/rguenther/trunk2-g/gcc/xgcc -B/home/abuild/rguenther/trunk2-g/gcc/ linker_plugin19653.c -fno-diagnostics-show-caret -fdiagnostics-color=never -flto -fuse-linker-plugin -lm -o linker_plugin19653.exe (timeout = 300) spawn /home/abuild/rguenther/trunk2-g/gcc/xgcc -B/home/abuild/rguenther/trunk2-g/gcc/ linker_plugin19653.c -fno-diagnostics-show-caret -fdiagnostics-color=never -flto -fuse-linker-plugin -lm -o linker_plugin19653.exe^M Executing on host: /home/abuild/rguenther/trunk2-g/gcc/xgcc -B/home/abuild/rguenther/trunk2-g/gcc/ linker_plugin19653.c -fno-diagnostics-show-caret -fdiagnostics-color=never -flto -fuse-linker-plugin -o linker_plugin19653.exe (timeout = 300) ... those appear to be from the lto and linker-plugin meta-testing.
