Afair, Michael pointed out that the relevant 
wording (that you quoted) was removed from the 
C standard and that at least two manuals 
explicitly allow mixing memalign an realloc.

And if I understood one of your messages 
correctly, the issue only surfaced with 
a simulator and is not reproducible on 
any platform (but I may have misunderstood, 
hence my question).

Finally, I believe you wanted to suggest to 
the maintainers of google-perftools to change 
the code, because the C libraries appear to 
change documentation in this regard (and the 
new documentation makes sense to you iiuc).

That is why I asked for some more information, 
to at least mention in the commit message that 
this is only a theoretical issue (in case I 
understand correctly).
