--- Comment #1 from Christoph Haag haagch@frickel.club --- Created attachment 126706 --> https://bugs.freedesktop.org/attachment.cgi?id=126706&action=edit gdb.txt assertion with full backtrace

With full debugging llvm and mesa I get an assertion instead:

janusvr: /home/chris/build/llvm-svn/src/llvm/include/llvm/Analysis/LoopInfoImpl.h:247: void llvm::LoopBase<N, M>::verifyLoop() const [with BlockT = llvm::BasicBlock; LoopT = llvm::Loop]: Assertion `std::any_of(GraphTraits<BlockT*>::child_begin(BB), GraphTraits<BlockT*>::child_end(BB), [&](BlockT *B){return contains(B);}) && "Loop block has no in-loop successors!"' failed.

backtrace full attached
