Summary: test_peepholer failing on HEAD
Initial Comment:
On WinXP with current CVS HEAD:
FAIL: test_folding_of_binops_on_constants
(__main__.TestTranforms)
------------------------------------------------------
----------------
Traceback (most recent call last):
File "../lib/test/test_peepholer.py", line 134, in
test_folding_of_binops_on_constants
self.assert_('(1000)' in asm)
AssertionError
and asm contains the big string 'x'*1000 instead.

Hmm, I don't see how we could get different results. After
a fresh cvs up and recompilation, I get:

Well, I'm using rt.bat from PCbuild to run the tests. That
deletes all the .pyc and .pyo files reachable from Lib before
running the tests. So, no, deleting .pyc doesn't matter here.
...\PCbuild>python rmpyc.py
81 .pyc deleted, 0 .pyo deleted
...\PCbuild>dir/s/b ..\Lib\*.pyc ..\Lib\*.pyo
File Not Found
...\PCbuild>rt test_peepholer
Deleting .pyc/.pyo files ...
14 .pyc deleted, 0 .pyo deleted
...\PCbuild>python -E -tt ../lib/test/regrtest.py
test_peepholer
test_peepholer
test test_peepholer failed -- Traceback (most recent call

About to run again without deleting .pyc/.pyo first:
Press any key to continue . . .
Terminate batch job (Y/N)? y
Is it possible, e.g., that you have an unchecked-in change on
your development machine?

Can you confirm that it works after deleting the pyc file?
If so, I'll bump the magic number.
