What glibc version?  (Please only use glibc-2.2.5 or later.)
How large is the chunk that you are trying to allocate and which fails?
Is 780MB the total size handed out to the application, including
mmap()ed chunks?  (There may be much more memory actually allocated
already.)
Please send the content of /proc/<pid>/maps when the problem occurs.
(Though I may not be able to reply over the next few days.)
