OK -- but the same question still applies: struct syment * value_search(ulong value, ulong *offset) { struct syment *sp, *spnext; if (!in_ksymbol_range(value)) return((struct syment *)NULL); How does it get past in_ksymbol_range()? What is the value of st->symtable[0].value and the passed-in "value"? Dave -- Crash-utility mailing list Crash-utility@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/crash-utility
