This is part of #3613 (closed) that never got fixed:

/** Assertion checking.  We don't ever compile assertions out, and we
    want precise control over the error messages, so we use our own
    assertion macros. */
#define obfs_assert(expr)                               \
  do {                                                  \
    if (!(expr))                                        \
      log_error("assertion failure at %s:%d: %s",       \
                __FILE__, __LINE__, #expr);             \
  } while (0)

#define obfs_abort()                                    \
  do {                                                  \
    log_error("aborted at %s:%d", __FILE__, __LINE__);  \
  } while (0)

and log_error() is:

/** Public function for logging an error and then exiting. */
void
log_error(const char *format, ...)
{
  va_list ap;
  va_start(ap,format);

  logv(LOG_SEV_ERR, format, ap);

  va_end(ap);
  exit(1);
}

This won't dump cores or backtraces back to the user.
