--- Comment #29 from Aurelien Jarno <aurelien at aurel32 dot net> --- (In reply to Richard Biener from comment #25) > Re-adding GCC 6 as regression, though graphviz is not gsoap. Indeed the patch that has been committed (or the same one backported to the GCC 5 branch) correctly fixes the gsoap issue. It doesn't fixes the graphviz one, that said while the issue looks similar it might actually be a different one.
