[0.4.x] plugins: Build fails with strict-aliasing violations
I tried to build with the following *FLAGS to optimize the build: -flto=4 -Werror=odr -Werror=lto-type-mismatch -Werror=strict-aliasing
The -Werror=* flags are important to detect cases where the compiler can try to optimize based on assuming Undefined Behavior (UB) cannot happen, and miscompile code that has UB in it. strict-aliasing issues are always bad but LTO can make them even worse.
I got this error:

cc1plus: some warnings being treated as errors
make[6]: *** [Makefile:519: G-Force.lo] Error 1
Originally reported downstream (hi @hartwork): https://bugs.gentoo.org/927006 Full build log: build.log
Most of the errors are fixed in master. The remaining ones are being addressed in https://github.com/Libvisual/libvisual/pull/291. They should work in C++11 and can be backported to 0.4.x.
and can be backported to 0.4.x.
…which we should do upstream (rather than only downstream in Gentoo), to be explicit about that.
