Can you please explain why the dlmalloc code depends on this? In my experience so far it has always been possible to avoid such warnings by trivial changes to the code (the tricky part was usually to understand what the exact problem was and what changes were necessary). > Instead of trying trying to work around the warnings, we use the per file > CFLAGs to disable the warnings via -fno-strict-aliasing. I tend to reject this patch. I would much rather have the problem fixed in the sources. Hushing up compiler warnings has never been a good idea.
