--- Comment #5 from Sergei Trofimovich <slyfox at gcc dot gnu.org> --- (In reply to Andrew Pinski from comment #1) > We definitely needs more information than this. It could very well be a bug > in LLVM too. > Have you tried compiling LLVM with -fsanitize=address ? (In reply to Andrew Pinski from comment #2) > How about -fwrapv ? Tried the following: - -fwrapv: no change, hangup still happens - -fsanitize=address: hangup disappears, no reports on stderr - -fwrapv -fsanitize=address: hangup disappears, no reports on stderr - -fsanitize=undefined: hangup disappears, no reports on stderr
