Lib\lib2to3\tests\data\, in test_with_statement, requires a variant of the with statement (multiple targets) that is not available in Python 2.6.  Compiling raises a SyntaxError.  This makes the 2.6.5 installer exit with an error message when asked to pre-compile all .pyc files, as reported in issue6716.

The fix is simply to remove the last three 'with' statements in function test_with_statement, around line 923 in Lib\lib2to3\tests\data\, as this is invalid code for this Python version.

The correct thing to do is actually to ignore when compiling the pyc files.

I have upload a patch for this problem by just removing the lines as Gabriel said.

Please check it out. Thanks.

Benjamin, ISTM that the tests in lib2to3/tests/data/py2_test_grammar aren't run at all, as part of regrtest. If so, the entire file could be removed.

True, but then it would become out of sync with the other branches.
The tests aren't run in the trunk either, but we keep the file there.

I have now fixed this with r83721, by excluding the file from compileall.
