Thankyou!
Whoops. Was trying to get the data structure built at compile time.
Anyway to get it to work within windows, I tried EditBin.exe but it didn’t
work. I set the reserve stack to 512Mb.
How did you get ld. from GCC9 to work for this target?

It seems that Nick was right that this hitting the stack limit.
The reason it's doing so is that you have a quite a lot of templates in your
C++ code.
The linker seems to segfault when it's trying to demangle this symbol
_ZNSt11_Tuple_implILj0EJN7General6Parser4NodeINS1_7KeywordILj4ELj2EEENS1_6StatesIJNS2_INS3_ILj5ELj3EEENS5_IJNS1_4SCPI3EndINS7_15CommandInternalIRKS4_JNS1_5ParamIfEENS7_5BlankILj0EEEEEEZNS7_7CommandISB
which is done in libiberty

This hits two VLAs expanding two structs of 16 bytes. However you have 1485065
entries in dpi.num_copy_templates
causing it to push the stack down (dpi.num_saved_scopes +
dpi.num_copy_templates) * 16 bytes. Which is 190129824 bytes, or 181mb and so
way over blowing your stack limit.
I tried with GCC 9 which seems to do a better job with the templates and it
works there. But I guess the real fix is to not use those VLAs in libiberty.
But I believe that's maintained by GCC if I'm not mistaken.
for now, you can work around it by increasing your ulimit.
