Bug #8253: Can't eval very long strings (SystemStackError)
https://bugs.ruby-lang.org/issues/8253

I have a very long string which is the output from a Solr server, RSolr gem fails to eval the response as a Ruby object because it is too long (> 640K). I have filed a detailed bug description here:
https://github.com/mwmitchell/rsolr/issues/61
The problematic response can be found here:
http://da.qcri.org/solr-response-46-70000.txt
It boiled down that Kernel.eval fails because the string is too long for the allocated stack.
File: vm.c
Function: vm_set_eval_stack
MACRO: CHECK_STACK_OVERFLOW

Is it just a limitation in the VM or the stack can have a dynamically larger size?
