Source file created by crash reporter

When compiling Viz.js (GraphViz for the web) the compiler segfaults while
compiling "lab.c" of GraphViz. I reduced the problem to:

emcc -ffast-math lab.c

<span class="quote">> emcc --version</span >
emcc (Emscripten gcc/clang-like replacement) 1.39.1 ((unknown revision))

<span class="quote">> /usr/lib/emscripten-llvm/clang --version</span >
clang version 10.0.0 (/srcdest/llvm-project
411f1885b655ea622fe124a87a6eadfd988d7a5e)</pre>
