ci failed for large files (>2GB) - diff: memory exhausted

Hi All

 

I have compiled RCS with 64-bit to support large files (> 2GB) and it is
working fine for initial revision. But from second revision onwards it
is failing if the file size >= 1.1 GB and I am getting the following
error. This error is more related to diff utility which is used by ci
command while check-in the file into RCS.

 

Error Message:

diff: memory exhausted

 

I did google for this error and I came to know that there some other
utilities to get rid of this error, but here I am not issuing diff
command manually (i.e., diff command is issued by ci command internally)
so I can't use the other available utilities/options. Is there anyway
get rid of this error like suppressing diff command while check-in or
compiling diff utility with large file support?

 

My server architecture is : SunOS hostname 5.9 Generic_122300-47 sun4u
sparc SUNW,Ultra-4

 

Thanks in advance for your help!
