--- Comment #14 from John Paul Adrian Glaubitz <glaubitz at physik dot fu-berlin.de> --- The issue still reproduces with gcc_4.9_4.9.3-3 in Debian which corresponds to SVN revision r226107 of the gcc-4.9 branch: Comparing stages 2 and 3 warning: gcc/cc1plus-checksum.o differs warning: gcc/cc1obj-checksum.o differs warning: gcc/cc1objplus-checksum.o differs warning: gcc/cc1-checksum.o differs Bootstrap comparison failure! gcc/d/ctfeexpr.dmd.o differs Makefile:19827: recipe for target 'compare' failed I have attached the stage 2 and 3 versions of gcc/d/ctfeexpr.dmd.o respectively and also disassembled both after stripping them to be able to generate a diff for the disassembled code. Unlike PR/target 67002, the diff seems rather large this time. Let me know if you need anything else, I have kept the full build of the compiler after it failed the compare target. Adrian
