--- Comment #3 from Marshall Clow (home) <mclow.lists at gmail.com> ---
Ok, I was wrong. Turns out that the part of the standard I quoted is for C++
allocation functions (i.e, replacements for operator new, or method calls in
allocators), not for functions that were hoisted from C.

Committed revision 220702 to fix the problem in <locale> (different from the
suggested fix, though).

Also, while looking at other calls to realloc in ios.cpp, I found some integer
overflows, as well as a bug in register_callback (__event_cap_ was never
getting updated).

Anyway, they're all better now. Sorry for the "invalid" tag.
