Obviously a bug. It occur because a more stringent fast-locals algorithm
was added in a2 (this fix a bug when "exec" staments assign to a local
and make jython more CPython compatible). The new algorithmt assume that
all locals have been detected correctly where the a1 would use a slower
string based local lookup when in doubt.

The trigger is the local assignments in list comprehension that wasn't
detected correctly. "s1" and "s2" and locals in defining block:

    pairs = [s2 for s1 in qs.split('&') for s2 in s1.split(';')]

A patch have now been checked into CVS.
