That GCC bug is fixed in Debian, and graphviz has been rebuilt. However dot still fails, see: https://buildd.debian.org/status/fetch.php?pkg=wayland&arch=mips&ver=1.10.0-1&stamp=1460114668 /usr/bin/dot -Tpng -oxml/wayland-architecture.png ../../../doc/doxygen/dot/wayland-architecture.gv Makefile:604: recipe for target 'xml/wayland-architecture.png' failed make[4]: *** [xml/wayland-architecture.png] Segmentation fault https://buildd.debian.org/status/fetch.php?pkg=wayland&arch=mipsel&ver=1.10.0-1&stamp=1460114941 /usr/bin/dot -Tpng -oxml/wayland-architecture.png ../../../doc/doxygen/dot/wayland-architecture.gv dot: emit.c:3874: bezier_bb: Assertion `bz.size % 3 == 1' failed. Makefile:604: recipe for target 'xml/wayland-architecture.png' failed Cheers, Emilio
