           Summary: glDrawElements: Invalid cast!
           Product: Mesa
           Version: 18.0
          Hardware: x86-64 (AMD64)
                OS: Linux (All)
            Status: NEW
          Severity: major
          Priority: medium
         Component: Drivers/Gallium/swr
          Assignee: mesa-dev at lists.freedesktop.org

example of using glDrawElements

The program "test" (see the attachment) crashes with this error:

[login3]$ export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:${PWD}/install/mesa1811/lib
[login3]$ export GALLIUM_DRIVER=swr
[login3]$ ml LLVM/4.0.0-GCC-6.3.0-2.27  #or "ml LLVM/5.0.0-GCC-6.3.0-2.27"
[login3]$ g++ hellogl.cpp -o test -lglut -lGL ; ./test

SWR detected AVX2 instruction support (using: libswrAVX2.so).

test:
/apps/easybuild/build/LLVM/4.0.0/GCC-6.3.0-2.27/llvm-4.0.0.src/lib/IR/Instructions.cpp:2592:
static llvm::CastInst* llvm::CastInst::Create(llvm::Instruction::CastOps,
llvm::Value*, llvm::Type*, const llvm::Twine&, llvm::Instruction*): Assertion
`castIsValid(op, S, Ty) && "Invalid cast!"' failed.
Aborted (core dumped)

Thank you for your help.
