Bug#872239: numexpr: Debug packages should not be removed

[Dmitry Shachnev]

Source: numexpr
Version: 2.6.2-1
Severity: serious
Justification: makes pytables FTBFS
Control: affects -1 src:pytables

Dear maintainer,

The changelog for numexpr 2.6.2-1 says:

  numexpr (2.6.2-1) unstable; urgency=medium

    [...]
    * Drop -dbg package declaration (now debug packages are automatically
      generated)

This is not true. The automatically generated dbgsym packages only contain
the debugging symbols for the C extension files. However, the former -dbg
packages contained the extensions built for Python debug interpreter:

  $ dpkg -L python3-numexpr-dbg
  /usr/lib/python3/dist-packages/numexpr/interpreter.cpython-35dm-x86_64-linux-gnu.so
  /usr/lib/python3/dist-packages/numexpr/interpreter.cpython-36dm-x86_64-linux-gnu.so
  [...]

These files are needed when you want to use numexpr with the debug
interpreter, i.e. /usr/bin/python3-dbg; and they are not present in the
automatic dbgsym packages. So please revert dropping the -dbg packages.

This was also discussed on debian-python mailing list several times, i.e.:
https://lists.debian.org/debian-python/2016/04/msg00093.html

I am setting the severity to serious to prevent the new upload from migrating
to testing; please feel free to downgrade it if you want.
