How do i extract a UBSan failure causing input from the seed corpus? Unlike ASan failures, libfuzzer is not writing the failure artifact sepeartely for UBSan. 22:04 < sipa> you can't, because the corpus only contains test inputs that pass 22:04 < sipa> libfuzzer binaries will write a separate crash-*** file for inputs that cause failure 22:04 < sipa> but you need to actually fuzz to find those 22:05 < sipa> asan vs ubsan shouldn't make a difference 22:05 < raj_149> thats what i expected. It wrote crash*** files for ASan. But just showing the UBSan failure in log. no artifact. how do i get them? 22:06 < raj_149> huh.. thats weird.. 22:08 < raj_149> is there any special dirrectory where those get written for core that i am missing? 22:08 < sipa> can you paste the output.somewhrre? 22:08 < sipa> the directory you're running in 22:08 < raj_149> yes i have reported the log here. https://github.com/bitcoin/bitcoin/issues/19278#issuecomment-646759265 22:13 < raj_149> Also. ubsan bug is not causing the fuzzer to stop. unlike an asan bug. 22:13 < sipa> hmm 22:13 < raj_149> the only flags I am using is -jobs=8 -workers=4 22:14 -!- Talkless [~Talkless@hst-227-49.splius.lt] has joined #bitcoin-core-pr-reviews 22:20 -!- slivera [~slivera@103.231.88.10] has joined #bitcoin-core-pr-reviews 22:41 < raj_149> ok i found some clue. using UBSAN_OPTIONS="halt_on_error=1" is producing the crash artifact in running directory. But its only producing it for the first crash and then exiting. How do i tell it to keep going and do the same for next crashes. halt_on_error doesn't seem like something i want here, but its atleast giving one artifact. Documentation of UBSAN_OPTIONS in internet is also very scarce. 22:54 < raj_149> One option is to fix the first one then move into next. But would love if someone can suggest a better way. 23:04 -!- Talkless [~Talkless@hst-227-49.splius.lt] has quit [Quit: Konversation terminated!]
