Purify complained about reading uninitialized memory in ast.c:752 of two bytes which corresponds to the type field. Looking into this, line 750 increments i without checking that there are in fact this many children. If you add the line: assert(i < NCH(n)); after line 750 you get an assertion failure when you run test_keywordonlyarg in the testsuite
