Also I was able to get a trace of this in valgrind, attached here. It's ver= bose and kind of lengthy, search for "Invalid read". Backtrace is the same as the others, and the read address matches what I se= e in the core dump. What is interesting is the "Use of uninitialized value" just before the invalid read, at the same place in the stack. It suggests that t= he invalid read is a consequence of operating on uninitialized data, in the red-black-tree implementation of C++ std::set. Unless our standard library is seriously broken, this looks like a case for upstream mesa to me. It's their internal data structures with a custom allocator. Did anybody already report it there? --=20 You are receiving this mail because: You are the assignee for the bug.=
