re: "why you cannot interface with Flex/Bison in the way you do and pick a different, real GC"
I would be grateful if you could give me some... pointers to the right direction. Even the integration of Flex/Bison was a hit'n'miss mission. The weird thing is that - given that I've been running tons of different benchmarks - most of the tests do work with _any_ GC. But _all_ of them, do run only with \--gc:regions turned on. That's what I find perplexing. Also, for the tests that _are_ running fine, regardless of the GC option being used, how is it possible that all different gc options result in more-or-less slower execution times?
