Hi, ASan's signal handler is catch SIGSEGV. It looks like your program is trying to dereference a nullptr. Unfortunately ASan doesn't seem to be able to produce a stacktrace in this case. I'd recommend running with gdb or lldb attached and disabling ASan's signal handler (set ASAN_OPTIONS=handle_segv=0 in your environment) so the debugger can catch the SEGV so you can work out where the nullptr dereference is happening.
