OFFTOPIC: core dumped with strcpy,atoi,sprintf.

Hi.
I hope you can help me. I have problems with some functions like
strcpy, atoi, etc and  would like to know the correct list where I have
to ask this:



I have compiled a program  under SCO Openserver, and  run succesfully.
But when  i compile the same program in Ubuntu  12.04,  i got a core dump.


Debugging the program, found that the core is generated  by atoi,
sprintf and similar functions; because that functions fails when
received  a null pointer (NULL). But, if  the functions received  an
empty string ("") the program continues and run succesfully.


Yes,  I should validate each input pointers. But, its odd that works in
SCO and not in Linux, and its odder that fails in functions like strcpy,
atoi, sprintf, etc.


I have a lot of programs that i should compile in boths operative
systems. And if you kown something that can  help me, really, really i'd
appreciate.  :-)


Regards.
