It definitely crashes during optimization of the trace produced by the JIT. I imagine that we could get somewhere by carefully inspecting the unoptimized operations that lead to the crash. Try enabling the dump with "PYPYLOG=jit-log-unopt:log", and then reproducing the crash. This should ideally leave behind a file called "log" with all the unoptimized loops seen so far, and the faulty one is the last one (i.e. the last section between "{jit-log-unopt" and "jit-log-unopt}"). A bientôt, Armin.
