--- Comment #9 from Djordje Baljozovic <djordje.baljozovic at ac dot rwth-aachen.de> --- (In reply to Andrew Pinski from comment #7) > A few questions, does `-fsanitize=undefined -fsanitize=address` report > anything? Does it work at -O0 and not just -O3? Does adding > -fno-strict-aliasing to the command line "fix" the crash? Are there any > warnings with `-Wextra -Wall` that might be causing an issue? Have not tested -O0 and -fno-strict-aliasing; will let you know if this fixed the problem. No warnings with -Wextra -Wall to my knowledge. Sincerely, George
