[aarch64-port-dev ] Building with BUILTIN_SIM generates SIGSEGV when running java -version

[Andrew McDermott]

Please disregard this - I had local changes which I had not reverted.

Or, if this is deliberately disabled, is there any value if I create a patch which replaces uses of 'new char[]' with, say, class stringStream in parts of the builtin simulator code?
