That's great news, since I haven't made any progress in my attempts. Can you try changing, in "jit.h" around line 1324 #define PAST_LIMIT() .... #define CHECK_LIMIT() .... #if 1 to #define PAST_LIMIT() .... #define CHECK_LIMIT() .... #if 0 ? Hopefully, the crash will then provide more useful information. -- You received this message because you are subscribed to the Google Groups "Racket Developers" group.
