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,
