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.
