dyung added a comment. We also saw this assert on our Windows build, and it also can be reproduced in Linux:
$ cat test2.c static char *getenv(char *) {} void foo() { getenv(""); } $ ~/src/upstream/879f5118fc74657e4a5c4eff6810098e1eed75ac-linux/bin/clang -c -O3 test2.c test2.c:1:27: warning: omitting the parameter name in a function definition is a C2x extension [-Wc2x-extensions] static char *getenv(char *) {} ^ test2.c:1:30: warning: non-void function does not return a value [-Wreturn-type] static char *getenv(char *) {} ^ clang: /home/dyung/src/upstream/llvm_clean_git/llvm/lib/Analysis/CGSCCPassManager.cpp:958: updateCGAndAnalysisManagerForPass(llvm::LazyCallGraph&, llvm::LazyCallGraph::SCC&, llvm::LazyCallGraph::Node&, llvm::CGSCCAnalysisManager&, llvm::CGSCCUpdateResult&, llvm::FunctionAnalysisManager&, bool)::<lambda(llvm::Function&)>: Assertion `RefereeN && "Visited function should already have an associated node"' failed. The key seems to be the special function getenv(). If I rename the function, the crash does not occur.
