>From the definition of CommandLine::Args::end() either ShortOpt or LongOpt may be NULL. However, any Args with LongOpt NULL will cause a segfault in CommandLine::Parse at this point: // Match up to a = against the list Args *A; const char *OptEnd = strchrnul(Opt, '='); for (A = ArgList; A->end() == false && stringcasecmp(Opt,OptEnd,A->LongOpt) != 0; A++); Checking for A->LongOpt == 0 before stringcasecmp, as in the attached patch, is sufficient to avoid this.
