New submission from Bob Ziuchkovski <bob.ziuchkovski at gmail.com>:
With current trunk, pypy's JIT produces different behavior between linux32 and
linux64 builds for the attached sample code. The attached sample code from
main.py calls a function with the same input args 10 times.
If run under linux32 JIT, the loop from main.py will produce the same results
each run through the loop. If run under linux64 JIT, after several iterations
of the loop, the results are different. However, if the JIT is disabled on
linux64 (--jit trace_limit=-1), the 10 iterations of the loop do produce the
correct result. Hence it looks like the sample code triggers a bug that is
specifically tied to 64bit JIT.
