How can I get the code backtrace?
This is some test result.

Is the program built with debug symbols?

Is the program built with debug symbols?

hi, I have the same question. My compilation instrution is

bazel build --compilation_mode=dbg --config=asan-libfuzzer tcmalloc/testing:memory_errors_test

And, it prints "*** Try rerunning with --config=asan to get stack trace of overflow ***"

Thanks for your help :)
