Thanks Matthew. This was Racket 5.0. I swore "unlimited" was set in DrRacket GUI. Maybe some bug where that was ignored? I'll check again but meanwhile I reverted temporarily to PLT Scheme 4.2.5. Another git bisect turned up a point where the behavior changed (before that I wasn't running out of memory) and I'm trying to figure out why. After I figure that out I'll pop the stack and go back to Racket 5.0 to confirm what's happening with that.

Again this is all on Windows 7 64-bit, in case that matters. Since Racket (and PLT Scheme) are 32-bit processes, 2 GB is the max they *could* get. But they never get 2 GB. Just 1 GB. On both PLT 4.2.5 and Racket 5.0, when I set "unlimited" in the GUI I have never, ever seen the DrXxx.exe process exceed 1 GB. It always tops out there and GC kicks in. If GC can't free up much, it just gets stuck "flatlined" there at 1 GB, and eventually the Visual C++ runtime error occurs. So: [1] At some point my code started using much more memory. That's my issue to figure out. Shouldn't need > 1 GB for this project. [2] Even so, 1 GB seems to be a limit even if "unlimited" is set.
