My C is very rusty but the traversal of SeqTableData doesn't seem correct.
It saves the seqtab->next pointer into next, frees seqtab and then
dereferences it.
Shouldn't that last line be: seqtab = next?

+ while (seqtab != NULL)
+ {
+ next = seqtab->next;
+ free(seqtab);
+ seqtab = seqtab->next;
+ }
