Warning: Return value of malloc()...

[<don...@is...>]

I think that this is the consequence of a recent change to
 http://hg.code.sf.net/p/clisp/clisp :
I notice in last night's build the following message whenever
the newly built image starts:
  Warning: Return value of malloc() = 7f924a51b010 is not compatible with type code distribution.
The image seems to work, but I suspect that someone will want to change
some code to fix whatever it is that causes that message.

Interestingly, this does not occur in the MT version.

Here are the two configure lines.
 ./configure CC='gcc -m64' --disable-maintainer-mode --with-debug --with-module=rawsock build-dir

./configure CC='gcc -m64' --with-threads=POSIX_THREADS --disable-maintainer-mode --with-debug --with-module=rawsock build-mt

The system that is doing the build:
$ uname -a
