Fix strict-aliasing warning in dlmalloc
This fixes the following warnings in dlmalloc seen with my gcc 4.6.

dlmalloc.c:1493: warning: dereferencing pointer 'p' does break strict-aliasing rules
dlmalloc.c:1493: warning: dereferencing pointer 'p' does break strict-aliasing rules
dlmalloc.c:1490: note: initialized from here
