It also definitely looks like a mesa bug to me. ./src/compiler/glsl/linker.cpp:link_shaders() calls ./src/compiler/glsl/linker.cpp:check_explicit_uniform_locations(), which returns -1 if ctx->Extensions.ARB_explicit_uniform_location is not set (which it doesn't have to be AFAICS), then assigns this -1 to an unsigned int variable and carries on using the value instead of treating this as an error. ** Changed in: mesa (Ubuntu) Importance: Undecided => Critical -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1585942 Title: Mesa causes a segmentation fault on arm64 (wrong count of uniform locations) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/mesa/+bug/1585942/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
