The main ones will be allocating/freeing memory unless you use  
cmem/sharemem (including passing around reference counted types),  
exception catching (your program's exception class won't be related to  
the library's exception class), anything involving global variables  
(either implementation or interface) in units that exist both in the  
library and in the program.
