JFYI, c-level assertion failures during build

['John Clements' via dev-redirect]

I’m currently in a state where calling `make` in my top-level racket directory results in output ending thusly:

…
raco setup: 1 making: <pkgs>/cldr-bcp47/cldr/bcp47/data
Assertion failed: (!(used && (pre_body->count == 1) && pre_body->vars[0]->optimize.known_val && ((Scheme_Type)(scheme_once_used_type) == (Scheme_Type)(((((intptr_t)(pre_body->vars[0]->optimize.known_val)) & 0x1)?(Scheme_Type)scheme_integer_type:((Scheme_Object *)(pre_body->vars[0]->optimize.known_val))->type))) && ((Scheme_Once_Used *)pre_body->vars[0]->optimize.known_val)->moved)), function optimize_lets, file ../../../racket/gc2/../src/optimize.c, line 7986.
make[1]: *** [plain-in-place] Abort trap: 6
make: *** [in-place] Error 2


My next step is to try a fresh checkout… any idea what’s going on here?
