Getting a segmentation fault when trying to build my GCC backend

I am currently trying to write a GCC backend for a new architecture, but when I try to compile it I get the following error message:

xgcc: internal compiler error: Segmentation fault signal terminated program cc1

The build is configured with the following command:

../gcc/configure --prefix=--prefix=$HOME/GCC-10.0.1 --disable-bootstrap --target=arch_name --enable-languages=c

How would I go about fixing this error so that I can build my backend?

As far as I am aware, I have implemented the target macro's, functions and insn patterns required to get GCC to build.

Sorry that the question is a bit vague, I am not sure what extra information I can provide. If more specific information is needed please let me know and I will edit the question.

Thanks in advance.
