[Bug c/31633] Calling an uninitialized function pointer does not trigger a warning

[pinskia at gcc dot gnu dot org]

------- Comment #1 from pinskia at gcc dot gnu dot org  2007-04-19 17:24 -------
Use -O1 if you want to find unitialized variables (including function
pointers):
[pinskia-laptop:gcc/objdir-noboot/gcc] pinskia% ./cc1 -quiet -W -Wall t5.c -O1
t5.c: In function 'foo':
t5.c:4: warning: 'bar' is used uninitialized in this function


This is documented as a limitation also.
