Here's how I configure GCC:
$ /n/08/rask/src/gcc/configure --target m32c-unknown-elf
--with-newlib--enable-sim --disable-gdb --disable-nls
--enable-languages=c,c++,java

This is how to reproduce the failure:

$ ./xgcc -B./ ~/__dprintf.c -S -dp -o /dev/null -mcpu=m32cm
/n/08/rask/src/gcc/newlib/libc/misc/__dprintf.c: In function '__dprintf':
/n/08/rask/src/gcc/newlib/libc/misc/__dprintf.c:73: internal compiler error: in
expand_expr_real_1, at expr.c:7109
