Bug#831125: polygraph: FTBFS with GCC 6: ContainerBodyIter.cc:75:22: error: no match for 'operator!=' (operand types are 'ofixedstream' and 'int')
Source: polygraph
Version: 4.3.2-3
Severity: serious
Tags: stretch sid
User: debian-qa@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
