  • Are you doing this just for fun, or because you need gcc-5.4? If the latter, then iirc it's available from the toolchain-r ppa Commented Feb 13, 2017 at 14:22
  • @steeldriver Your distinction between fun and need escapes me. I am doing it because I want to test the installation of 4.9.4 with anything. So I do it with 5.4.0 (if not 6.3.0) which I may wish to use at my earliest resolution. If you can expand on the relevance of iirc to this compilation failure, the readership will appreciate.

  • What I meant was if all you want is a version of gcc that is newer than that provided by the Ubuntu 14.04 repository, you can install 4.9.4, 5.4.1, and/or 6.2.0 simply by enabling the ppa I referred to in my earlier comment - no compiler compilation required Commented Feb 13, 2017 at 19:53

    @steeldriver Thanks, clear. I am still interested in pinpointing the cause of this problem. In one computer this proof works well, in another it doesn't, starting from assumed equal conditions. So I would like to frame the pitfall. Commented Feb 14, 2017 at 10:55
