sqlite database stack smashing while putting epoch time into integer field

I use sqlite database and it has one column for epoch time, I use its type as INTEGER because I don't find any other suitable type for that. When I try to add data in that field through my C program it shows me * stack smashing detected *. probably it is because i try to put epoch time to INTEGER field. But it allows only following types. The types supported by database: text,integer,real,blob,null. what would be suitable type and if it is INTEGER how to remove this error.
