New description:

 REVISIONS from R1/alpha1 through r34335 exhibit the following behavior:

 While trying to configure a gcc build I noticed configure said:

 "checking for working mmap... no"

 I extracted the test program from the configure script and it fails in a
 malloc.  I have added printfs to the program so as to make it more
 descriptive.  The error printed is: "data3 null".  The failing line is:
 data3 = (char *) malloc (pagesize);

 To compile this program, simply: gcc mman.c -o mman
 And run ./mman

 I am running revision 34251, gcc2hybrid.  The program fails if I compile
 it with gcc2.95.3-haiku-090629 or if I compile it with gcc 4.4.2 (from joe
 protsko).

 THE ABOVE BEHAVIOR WENT AWAY in r34336 from 11/29/09 09:20:58
