Little patch

[David CARLIER]

Hi all,

I just had a short chat with otto and would like to know if this little
patch would be considered. The reasoning is while debugging a program I got
a segmentation fault inside the loop as pool was NULL probably due to the
fact that malloc_init was not called first.

Thanks in advance.

Kind regards.
