    • HP C/aC++ B3910B A.06.16 [Nov 26 2007]

    • Compiler Warning

    Description

      This warning is obviously incorrect. It goes away with optimization.

      $ cat t.cpp && aCC -V -c +w t.cpp
      int bar () {
      const char *s = 0;
      if (!s)
      s = ";";

      return *s;
      }

      aCC: HP C/aC++ B3910B A.06.16 [Nov 26 2007]
      "t.cpp", line 6, procedure bar: warning #20200-D: Potential null pointer
      dereference through s is detected (null definition:t.cpp, line 2)
