Hello, I tried 2.7.8 and it does not happen, and I tried hg branch 2.7 and it does, obviously that is an issue of Nuitka, that Nuitka will face more widespread, once 2.7.9 gets released.
However, check out this: [> /opt/python27_hg/bin/python Python 2.7.8+ (2.7:e6c7a5a94a1d, Sep 16 2014, 08:49:10) [GCC 4.9.1] on linux2 Type "help", "copyright", "credits" or "license" for more information. >>> > python Python 2.7.8 (default, Sep 9 2014, 22:08:43) [GCC 4.9.1] on linux2 Type "help", "copyright", "credits" or "license" for more information. Can we get the "+" in the Debian version too. In the past, there were similar backports of bug fixes, where Nuitka with its goal of bug compatibility had checked against the "+" sign to tell that it's a Debian version of Python with extra fixes included. This was really helpful to tell that it's not a baseline version. In the concrete case, I can make a run time check to see if the new behaviour is needed or not. But that is not generally the case. In terms of solution, I am not so sure yet, how f2 and f3 can be made to differ, it is going to need a new upstream release. I hope to find a solution during the week though. Yours, Kay
