2GB limit

[Dirk Wetter]

hi,

malloc/malloc.c says:
----
 This work is mainly derived from malloc-2.6.4 by Doug Lea
  <address@hidden>, which is available from:
                 ftp://g.oswego.edu/pub/misc/malloc.c
  Most of the original comments are reproduced in the code below.

so, why is the ancient version still being used?

according to ftp://g.oswego.edu/pub/misc there were major updates
between 2.6.4 and 2.7.0, and at least the size grew from 98k to
174k.

with the right kernel we weren't able with glibc 2.2.x/2.1.3 to malloc
more than 2GB under the i386 architecture. using malloc 2.7.0 from
Doug Lea instead and do a mallopt(-4,0) first, we're getting closer to
3GB...

are there plans to upgrade the malloc version or to fix the old code?

cheers,
        ~dirkw
