Is there something wrong with the version on libstdc++ on my system? (Debian testing) This was happening on revision 5857bf5d1e5a5ffe5ae51a38514ee55495c0cc69 -------------------------------------------------------------- I...

Thanks everyone! What are the best tools/techniques to expose such non-deterministic behavior? My hope is to reproduce it on a smaller test (e.g. use some sanitizer and thus make the compiler *fail* when building the test) - Currently these failures only tell me “there is some bug in your code” without any hints where to look for it.

Hi, I'm trying to build llvm (git monorepo) on Ubuntu 18.04 with EXPENSIVE_CHECKS enabled and running into various errors compiling SourceMgr.cpp, depending on which host compiler I use. For example with GCC: $ CC=gcc-8 CXX=g++-8 cmake -GNinja -DCMAKE_BUILD_TYPE=Debug -DLLVM_ENABLE_EXPENSIVE_CHECKS=ON ~/git/llvm-project/llvm/ && ninja ...
