--- Comment #5 from Martin Jambor <jamborm at gcc dot gnu.org> ---
Sorry, but I still cannot reproduce it.  I have checkout out the
latest gcc_5-branch (rev 232044) and configured it (on an
x86_64-linux) with

../src/configure --prefix=/home/mjambor/gcc/5/m68k/ --target=m68k-elf
--enable-languages=c --enable-checking=release --disable-bootstrap
--disable-libssp --disable-tls --enable-threads=single

Then I build the compiler simply with make (which fails afterwards
because it cannot build libgcc without other cross m68k tools but I do
get cc1).  Then I run cc1 on the provided example:

~/gcc/5/cross/gcc/cc1 -O2 unwind-dw2.i -g -auxbase-strip unwind-dw2.o
-g -O2 -fbuilding-libgcc -fno-stack-protector -fexceptions
-fvisibility=hidden -quiet

and I get only warnings, no ICE.  Can you please try to find any
difference in between my setup and yours which makes the issue
non-reproducible for me?  Thanks.
