The upstream failure was described as a gsoap issue, and upstream fixed that, however, dot failure is related but not fixed upstream. We successfully tested two different patches (one for backend code, other for arch code) for GCC that solves the issue, but stream is undecided in which to apply. Compiling graphviz with -fno-ipa-sra helps and makes the issue go away. The other option would be to disable graphs. While GCC upstream decides, I would prefer to build graphviz with -fno-ipa-sra, at least for mips/mipsel architectures. Would that be fine with graphviz maintainer? Failing that we should fallback to disable graphs in wayland package and many others which might need and have already done so. Regards, -- Hector Oron
