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
