The bug is in the removal of trivial UnspecifiedSequence in Cabs2Cil. The code uses a Cil_datatype.Stmt.Hashtbl, but in Cabs2Cil all sid seem to be -1. I will use an association list instead, but there are obvious efficiency concerns. Also, I'm not sure (==) is correct at this stage. Virgile, it seems you wrote the original code, can you check the patch? |
