Package: upx-ucl
Version: 3.91-1
Severity: important
User: [email protected]
Usertags: ftbfs-gcc-6 gcc-6-misleading-indentation
This package fails to build with GCC 6. GCC 6 has not been released
yet, but it's expected that GCC 6 will become the default compiler for
stretch.
Note that only the first error is reported; there might be more. You
can find a snapshot of GCC 6 in experimental. To build with GCC 6,
you can set CC=gcc-6 CXX=g++-6 explicitly.
