I am sorry if the post was not clear enough. My 3.2.3 build appears to be just fine and I have been using it for many months now. It does fail many of the tests, but nonetheless seems to generate good code. The ICE was caused by the first stage binary of 4.6.3 while building libgcc.

I will try a few things suggested by Thorsten, one at a time. If that does not work out I will try an interim build.
The biggest challenge on the NeXT is that the libraries are approx. 20 years old. What is there of POSIX, is very broken, and many of the standard c library functions are completely obsolete. So even once a compile is built and works well, many tests tend to fail.
Thank you for your suggestions!
