[Python-apps-team] Bug#682652: cython: Cython might cause problematic code when trying to build using gcc-4.7

[Andreas Tille]

Package: cython
Severity: normal

Hi,

there is some evidence that cython from testing/unstable as well as from
experimental (!) generates code which does not compile when using
gcc-4.7.  I have no idea whether packages in Wheezy might be affected -
I guess autobuild-test would have unrevealed this, but it seems it is
not a specific issue of the software which I asked for help at
debian-mentors list.  To get the full story it is advisable to read
this mail:

In the response[0] Sebastian Ramacher <sebastian at ramacher.at> said:

  As it seems, the fix has been merged after the 0.16 release. The patch to solve
  this in cython can be found at [1].

  Until this is fixed one can try to add spaces between PY_FORMAT_SIZE_T and the
  quotation marks in the file generated by cython.

So it would be nice if you might consider an upload - at least to
experimental - featuring the patch which would enable building this
project using gcc-4.7.

In case you have different plans because no other released package is
affected by this problem please let me know some estimated time until
you consider fixing the problem.  If it might take longer than say about
1 month I would consider releasing the packagin question for the moment
without Cython support or explicitely forcing gcc-4.6.

Kind regards and thanks for maintaining Cython

    Andreas.
