Re: multithread realloc()

realloc() doesn't seem to behave in multi-threading environments.

I have a memory unit which wraps all of malloc(), calloc(), realloc(),
free(), and a unit testing unit that vigorously checks the validity of
all of these. They all work as expected in both single and multi-
thread environments, with the sole exception of realloc() NOT working
in a multi-thread environment. (It works fine in a single thread.)

Google search shows that realloc() has been implemented incorrectly
for thread-safe usage in other compilers, so it's possible that it's
also incorrect in MSVC++ 8.0 (my compiler). But, I haven't found any
references that state this.

It's a rarely used function, and you have to pound the system pretty
hard in order to get it to fail AT ALL, so it could be that no one has
gotten bit, yet. But, it's more probable that I'm just missing
something...

Has anyone else witnessed such behaviour?
