[cvsnt] Bug in cvsnt admin command(-o option)

[Дмитрий Жилин]

Hi,
We have found a serious bug in the cvsnt admin command(-o option)
When this command used to outdate some revision from a compressed repository file ,
the file becames corrupted(no one can checkout it).

Example:
cvs add -kBz some_file.bin
cvs ci -m first_rev some_file.bin

//change file ,then commit it:

cvs ci -m second_rev some_file.bin

//remove revision 1.2
cvs admin -o1.2 some_file.bin

//try to checkout the file

cvs co some_file.bin

//we get reply:
cvs [server aborted]: out of memory; can not allocate 1380930350 bytes

the same command ,trace level 2
08:41:45:   -> Tracelevel set to 2.  PID is 920

08:41:47:   -> unlink_file(CVS/Entries.Log)
08:41:47:   -> unlink_file(CVS/Entries.Extra.Log)


We hope that the bug will be removed in new releases.

Thank you for support.
