"ERROR: general (de)compression error in srep:m3f:mem256mb" with large directory

[GoogleCodeExporter]

What steps will reproduce the problem?

I tried to compress a large directory with FreeArc 0.67, May 22 2012). It has 
302,009 total files and 59,439,907,806 total bytes.

I have used these options:

-s; -ma- -m=dispack+srep:m3f:mem256mb+delta+lzma:ultra:170mb

After some time (I think freearc has created a temporary file), I get this 
error message:

ERROR: general (de)compression error in srep:m3f:mem256mb

I have got 8GB of RAM in my PC.

it may be one of the following:

1. lack of space on temporary drive. use -wd:\dir where d: has at least 120 gb 
free
2. ram shortage, that can be solved by using external lzma-x64 from addons 
directory

try with just -m=lzma:ultra:170mb - if it fails then it's second situation, 
otherwise it's the first one

I've tried it a few more times and found the real problem: srep tried to 
allocate more than 4GB of RAM when using m3f. I am now using srep:m2f:mem256mb 
which seems to use about 1.7 GB of RAM, its working now

you may download http://freearc.org/download/research/srep30.zip and replace 
srep.exe with srep64i.exe
