That value is obtained from ao_string_tokenize( pczOptStr );
Memory management structures have become corrupt.
In chasing this a bit, I did discover a bug I introduced:
This assert became obsolete in longOptionFind():
do {
if (SKIP_OPT(pOD)) {
if ( (pOD->fOptState != (OPTST_OMITTED | OPTST_NO_INIT))
|| (pOD->pz_Name == NULL))
continue;
}
else assert(pOD->pz_Name != NULL);
It now means that the entry should be ignored. The correct form is now:
do {
/*
* If option disabled or a doc option, skip to next
*/
if (pOD->pz_Name == NULL)
continue;
if ( SKIP_OPT(pOD)
&& (pOD->fOptState != (OPTST_OMITTED | OPTST_NO_INIT)))
continue;
If this fixes the problem, I'll be a happy camper and not chase it any more. :)
Thanks -Bruce
