bug received in commit operation

Hi,
I have installed a cvs server on a solaris 5.8 (downloaded binary from  http://ftp.cvshome.org/unix/sunos/cvs-1.11.2-SUNOS-5.6.gz)
and access it from nt machines in the pserver protocol.
for one commit I got the following message:

CVSROOT: :pserver:itair@shemesh:/usr/local/cvsDB (password authentication)

TCL is *not* available, shell is disabled

cvs commit -m "no message" dealmgr.jpx (in directory D:\DEVELOPMENT\servlets\dealmgr\)

cvs [server aborted]: received abort signal

Assertion failed: ptr >= rcsbuf_buffer && ptr < rcsbuf_buffer + rcsbuf_buffer_size, file /u/scjones/cvs-nightly/src/rcs.c, line 1095

*****CVS exited normally with code 1*****

When I switched back to version 1.11.1p1 the operation worked fine.
The clients are the cvsgui dll (cvs2ntlib.dll which I believe correspond to ver 1.11.1p1)

Thank you,

Ariel Kroszynski.
