--- Comment #2 from xperience at interia dot pl 2013-04-09 20:03:30 UTC --- Compiler ICE's during compile phase, without LTO. Previous versions of GCC ie. 4.7.1 or 4.6.3 doesn't ICE, and output of gcc -O3 -mtune=native -march=native -fomit-frame-pointer -pipe -floop-interchange -floop-strip-mine -floop-block -fgraphite-identity -floop-parallelize-all -E -v - </dev/null 2>&1 | grep cc1 is /usr/libexec/gcc/x86_64-pc-linux-gnu/4.8.0/cc1 -E -quiet -v - -march=bdver2 -mcx16 -msahf -mno-movbe -maes -mpclmul -mpopcnt -mabm -mlwp -mfma -mfma4 -mxop -mbmi -mno-bmi2 -mtbm -mavx -mno-avx2 -msse4.2 -msse4.1 -mlzcnt -mno-rtm -mno-hle -mno-rdrnd -mf16c -mno-fsgsbase -mno-rdseed -mprfchw -mno-adx -mfxsr -mxsave -mno-xsaveopt --param l1-cache-size=16 --param l1-cache-line-size=64 --param l2-cache-size=2048 -mtune=bdver2 -fomit-frame-pointer -floop-interchange -floop-strip-mine -floop-block -fgraphite-identity -floop-parallelize-all -O3 it seems that compiler will not ICE when i don't have -floop-parallelize-all in my CFLAGS full command from makefile: libtool: compile: gcc -DHAVE_CONFIG_H -I. -I../.. -I../.. -I../../gegl -I../../gegl -I../../gegl/property-types -I../../gegl/property-types -I../../gegl/buffer -I../../gegl/buffer -I../../gegl/opencl -I../../gegl/opencl -pthread -I/usr/include/glib-2.0 -I/usr/lib64/glib-2.0/include -I/usr/include/babl-0.1 -O3 -mtune=native -march=native -fomit-frame-pointer -pipe -floop-interchange -floop-strip-mine -floop-block -fgraphite-identity -floop-parallelize-all -mmmx -msse -ftree-vectorize -ffast-math -Wall -Wdeclaration-after-statement -Wmissing-prototypes -Wmissing-declarations -Winit-self -Wpointer-arith -Wold-style-definition -DG_LOG_DOMAIN=\"GEGL-\"__FILE__ -MT gegl-processor.lo -MD -MP -MF .deps/gegl-processor.Tpo -c gegl-processor.c -fPIC -DPIC -o .libs/gegl-processor.o
