I tried building again (on another machine) and it did not get involved in this error. I doubt that it might be environment dependent.
I would suggest you report this issue to the mainstream with machine details (OS, CPU, etc) for further help.

I build again, successed, looks like this bug can not reproduce.

I guess it's the library's bug. For now I simply disabled test execution in PKGBUILD.

To versusvoid:
I've uploaded a patch for this issue.
Please notify me if it still failed to build the package.

To versusvoid:
After I apply the patch, I found it builds and passes with warnings with gcc 5.3.0.
What error message did you encounter?

versusvoid commented on 2016-04-11 13:24

Build fails on gcc 5.3.0. This commit ( fixes the building, yet test fails anyway.
