Hi,
Building and installing gcc-4.1.1 on cygwin failed in the final make install
step. Here's my script:
../gcc-4.1.1/configure --with-gcc --with-gnu-ld --with-gnu-as --enable-threads
--disable-nls --enable-languages=c,c++ --disable-win32-registry
--disable-shared --disable-sjlj-exceptions --without-x --enable-interpreter
--enable-hash-synchronization --enable-libstdcxx-debug
make CFLAGS="-O2 -fomit-frame-pointer" CXXFLAGS="-mthreads
-fno-omit-frame-pointer -O2" LDFLAGS=-s bootstrap 2>err.log
on make install, the ICE occurs here:

Additional notes:
Removing the -O2 option makes the ICE occur a bit later in eh_alloc.cc:183.
