[Python-Dev] Nasty new bug in test_longexp

[Tim Peters]

Fred, I vaguely recall you touched something here recently, so you're top o'
the list.  Smells like an uninitialized variable.

1 of 4:  test_longexp fails in release build:

C:\PCbuild>python ..\lib\test\regrtest.py test_longexp
test_longexp
test test_longexp failed -- Writing: '\012', expected: ' '
1 test failed: test_longexp

2 of 4:  but passes in verbose mode, despite that the output doesn't appear
to match what's expected (missing " (line 1)"):

C:\PCbuild>python ..\lib\test\regrtest.py -v test_longexp
test_longexp
test_longexp
Caught SyntaxError for long expression: expression too long
1 test OK.

3 of 4:  but passes in debug build:

C:\PCbuild>python_d ..\lib\test\regrtest.py test_longexp
Adding parser accelerators ...
Done.
test_longexp
1 test OK.

4 of 4: and verbose debug output does appear to match what's expected:

C:\PCbuild>python_d ..\lib\test\regrtest.py -v test_longexp

Adding parser accelerators ...
Done.
