When run against the released clang 3.0:

$ clang-mp-3.0 --version
clang-mp-3.0(46723) malloc: *** error for object 0x14d2674: Non-aligned pointer
being freed
*** set a breakpoint in malloc_error_break to debug
clang-mp-3.0(46723) malloc: *** error for object 0x14d2674: Non-aligned pointer
being freed
*** set a breakpoint in malloc_error_break to debug
clang-mp-3.0(46723) malloc: *** error for object 0x14d2674: Non-aligned pointer
being freed
*** set a breakpoint in malloc_error_break to debug
clang version 3.0 (tags/RELEASE_30/final)
Target: i386-apple-darwin9.8.0
Thread model: posix

The output of example.c when compiled for -arch ppc (powerpc-apple-darwin9) is
still:

offsetof(struct badsize,f4) = 24
  sizeof(struct badsize)    = 32

but it should be:

offsetof(struct badsize,f4) = 20
  sizeof(struct badsize)    = 28
