Bug#831097: eclipse-pydev: FTBFS with GCC 6: plugins/org.python.pydev/pysrc/pydevd_attach_to_process/linux/attach_linux.c:237:25: error: expected initializer before 'pydevdTracingMod'

[Lucas Nussbaum]

Source: eclipse-pydev
Version: 3.9.2-4
Severity: serious
Tags: stretch sid
User: debian-qa at lists.debian.org
Usertags: qa-ftbfs-20160713 qa-ftbfs
Justification: FTBFS with GCC 6 on amd64

Hi,

During a rebuild of all packages in sid using the gcc-defaults package
available in experimental to make GCC default to version 6, your package failed
to build on amd64. For more information about GCC 6 and Stretch, see:
- https://wiki.debian.org/GCC6
- https://lists.debian.org/debian-devel-announce/2016/06/msg00007.html

Relevant part (hopefully):

About the archive rebuild: The rebuild was done on EC2 VM instances from
Amazon Web Services, using a clean, minimal and up-to-date chroot. Every
failed build was retried once to eliminate random failures.
