Hi, Compiling libtorrent-0.12.6 using "-fgraphite-identity" ends up with an ICE. Disabling that flag "fixes" the problem. The bail-out message is at the bottom of this report. The same compilation with exactly the same flags performed on host/target/build triplet x86_64-pc-linux-gnu does not show that error and compiles fine.
I am no regular submitter for bug reports and no expert with gcc. If you need more info please tell, I'll try to provide it. For now I leave it with the .cc file and the .ii file. /bin/sh ../../libtool --tag=CXX --mode=compile i686-pc-linux-gnu-g++ -DHAVE_CONFIG_H -I. -I../.. -I. -I./.. -I../.. -v -save-temps -march=native -O2 -pipe -floop-interchange -floop-strip-mine -floop-block -fgraphite-identity -fvisibility-inlines-hidden -DNDEBUG -fvisibility=hidden -I/usr/include/sigc++-2.0 -I/usr/lib/sigc++-2.0/include -c -o dht_router.lo dht_router.cc libtool: compile: i686-pc-linux-gnu-g++ -DHAVE_CONFIG_H -I. -I../.. -I. -I./.. -I../.. -v -save-temps -march=native -O2 -pipe -floop-interchange -floop-strip-mine -floop-block -fgraphite-identity -fvisibility-inlines-hidden -DNDEBUG -fvisibility=hidden -I/usr/include/sigc++-2.0 -I/usr/lib/sigc++-2.0/include -c dht_router.cc -fPIC -DPIC -o .libs/dht_router.o i686-pc-linux-gnu-g++: warning: -pipe ignored because -save-temps specified Using built-in specs.
