...removed from DSA, the interface never returns MustAlias results. I guess it may not be possible to get 'MustAlias' results from DSA. Will it be possible to modify the DSA code so that every heap DSNode tracks all possible malloc() calls it comes from? Thanks for your help.

...o analysis algorithm for your work. In fact, my task can be solved in a simpler (while less elegant) way. If I want to find pointers must-alias with a malloc() call, I can create a new variable storing the result returned by the malloc() when it is called. Thanks for your help.

...ariable. In my task, I want to fix leaks in the C source code rather than relying on runtime libraries. Now, I think it's not necessary to use BBAC in my task. Maybe I will change my idea if I find too few bugs can be fixed without relying on any runtime libraries. Thanks a lot.
