This form of macro expansion is obsolete - I hope that the community agrees on this. Crashes for many more cases then just the one you mentioned. Its a really hard and bugrone to mimic the preprocessor, thus we seek to substitute this with the clang's preprocessor implementation. I recommend pushing an XFAIL lit test demonstrating the current limitation (without your proposed fix), while we can show that this will pass after we accept my patches. For the record those are in an early phase at D93222 <https://reviews.llvm.org/D93222>. ================ Comment at: clang/lib/StaticAnalyzer/Core/PlistDiagnostics.cpp:1241 if (TheTok.getIdentifierInfo() == VariadicParamII) { - TStream.injectRange(PrevParamMap.at(VariadicParamII)); + if (PrevParamMap.find(VariadicParamII) != PrevParamMap.end()) + TStream.injectRange(PrevParamMap.at(VariadicParamII)); ---------------- Btw this lookup supposed to be successful. Always. Which suggests me that there are even more logic bug lurking there. Without using 'at' here we wouldn't notice it, which is lucky.
