bootstrap of gcc-3.5-20040620 on Darwin 7.0.1 hangs (== never completes) here:

  -c ../../gcc-3.5-20040620/gcc/config/darwin-crt2.c -o crt2.o

after attaching gdb onto xgcc:

(gdb) attach xgcc

 I get the following backtrace:

GCC was bootstrapped like this:

mkdir /tmp/gcc
mkdir testbuild
cd testbuild/
../gcc-3.5-20040620/configure --prefix=/tmp/gcc
make bootstrap STAGE1_CFLAGS="-no-cpp-precomp -Wa,-force_cpusubtype_ALL -g"

If you want to see what is going on I can give you ssh access to my x86 Darwin box. Contact me by 
mail for this.
