--- Comment #12 from Georg Koppen <gk at torproject dot org> --- (In reply to Maxim Ostapenko from comment #10) > I've build Firefox locally with clang with optimizations disabled > (CFLAGS="-fsanitize=address -fsanitize-recover=address -O0") and got pretty > the same backtrace: What clang version/firefox version and build commands did you use for getting a clang build that crashes? Using the clang I have on my Debian machine + mozilla central does not seem to be enough.
