This happens both on gcc-4.8 and gcc-4.9, here's the excerpt from 4.8 [1]: Comparing stages 2 and 3 warning: gcc/cc1objplus-checksum.o differs warning: gcc/cc1-checksum.o differs warning: gcc/cc1plus-checksum.o differs warning: gcc/cc1obj-checksum.o differs Bootstrap comparison failure! gcc/d/ctfeexpr.dmd.o differs > - 5.something doesn't bootstrap because of c#19 > > ... right? Yeah, that seems to be unrelated. Sorry for the confusion.

Heh. I could try to talk to Nobuhiro again. Maybe he has some ideas where to get hold of faster SH4 hardware.
