I'm using a native compiler and I'm not sure how easy it will be to reproduce the failure, as it happens during stage3 build using the compier from stage2 when on "regclass.c" source. regclass.c passes the compilation when cc1 from stage1 is used. I've tried to get a backtrace using gdb, but I'm getting the following error from gdb: (gdb) b main Breakpoint 1 at 0x1009eac0: file ../../gcc/gcc/main.c, line 35.
