Backing down to xfree86-4.4.0, or using -O2, or not using -no-strict-aliasing, or using gcc-4.0.0, makes the problem go away. I'll attach a reduced testcase. To reproduce, do $ arm-unknown-linux-gnu-gcc -O3 -fno-strict-aliasing -c fontutils.i Error is fontutils.i:44: internal compiler error: in verify_local_live_at_start, at flow.c:546 Is this the same problem, or should I file a new report? -- What |Removed |Added ---------------------------------------------------------------------------- CC| |dank at kegel dot com, | |nagaraja at ncoretech dot | |com http://gcc.gnu.org/bugzilla/show_bug.cgi?id=17810
