Bug#822716: firefox: FTBFS with GCC 6: 'malloc' was not declared in this scope

[Martin Michlmayr]

Package: firefox
Version: 45.0.2-1
Severity: normal
User: debian-gcc at lists.debian.org
Usertags: ftbfs-gcc-6

This package fails to build with GCC 6.  GCC 6 has not been released
yet, but will probably come out this week.

You can find GCC 6 in unstable (gcc-6).  To build with
GCC 6, you can set CC=gcc-6 CXX=g++-6 explicitly.

You may be able to find out more about this issue at
https://gcc.gnu.org/gcc-6/changes.html
