Change subject: KUDU-2433. Don't try to symbolize a nullptr ...................................................................... KUDU-2433. Don't try to symbolize a nullptr Don't try to symbolize a nullptr when walking the stack. It may be possible to get a null pc in the case of unwinding through a stack frame in a library that wasn't built with frame pointers, or if the stack was corrupted. Attempting to symbolize a nullptr with this code path will overflow the null pointer from 0 to UINT64_MAX, which causes a fatal exception in UBSAN builds.
