when compiling newlib with mcore-unknown-elf-gcc (v4.1.0) I get an internal
compiler error.

Compiler configure line

../gcc-4.1.0/configure   --target=mcore-unknown-elf --disable-libssp
--enable-languages=c

The command line that triggers the bug is

mcore-unknown-elf-gcc
-B/home/peter_jan/mcore/build-newlib/mcore-unknown-elf/big/newlib/ -isystem
/home/peter_jan/mcore/build-newlib/mcore-unknown-elf/big/newlib/targ-include

-g -O2 -mbig-endian -c
../../../../../../newlib-1.14.0/newlib/libc/stdlib/dtoa.c --save-temps

Here is the compiler output

../../../../../../newlib-1.14.0/newlib/libc/stdlib/dtoa.c: In function
