|Subject:||failing build with newer GCC versions|
see perlmonks threadfor discussion. The Filter::Crytpo CPAN Testers matrix ( show similar results on any mswin with perl newer than 5.25.10. Looking at the difference between 5.25.10 passing ( and 5.26.0 failing ( , the thing that jumps out at me is the change from gcc 4.9.2 jumping to gcc 7.1.0. This 5.26.1 linux fail ( uses gcc 6.3.0 and gives the same error messages during compilation, whereas this 5.26.1 linux pass ( uses gcc 5.4.0. This all seems to point to the version of gcc. If gcc version is 4.9.2 or 5.4.0, it compiles; if version is 6.3.0 or 7.1.0, it does not compile, and the module doesn't install.
