[Bug tree-optimization/26144] with -O3 and pointer casts, gcc skips if

[pinskia at gcc dot gnu dot org]

------- Comment #3 from pinskia at gcc dot gnu dot org  2006-02-09 01:02 -------
You are violating aliasing rules which is why this does not work at -O3. 
Either access the variable ptr as  a "struct blah *" or use
-fno-strict-aliasing.
