Hello !

1) The crash.

When I add the new directory to the project, copy some files to it and
then execute "cvs add *.*" in that directory _server_ cvs.exe process

This crash can be fixed with the following patch:

Index: add.c
RCS file: /usr/local/cvs/cvsnt/src/add.c,v
retrieving revision
diff -u -U5 -r1. add.c
--- add.c       14 Oct 2004 15:18:47 -0000

+           char *tmp = argv[i];
            for (j = i; j < argc - 1; ++j)
                argv[j] = argv[j + 1];
+            argv[argc - 1] = tmp;
            /* Check the new argv[i] again.  */

Another way to fix the crash is to make a copy of the
'argument_vector' in function 'static void do_cvs_command (cmd_name,
command)' in file 'server.c' and free memory using copied values.

2) Ideas about save crashdump feature.

I think it should be configurable. Usually cvs is installed on the
server and nobody sees its dialog "Do you want to save crashdump ?".
In the case above the directory in repository remains locked whilst
this dialog is open.

I think there should be the following options:

1) do not save crashdumps at all

2) save brief information about crashdump in text file adding
timestamp to the filename.

3) save full crashdump automatically if there is enough disk space
(greater than some configurable number of Mb) adding timestamp to the

4) ask the user.

PS. This crash without patch was reported to the
cvsnt-crashdumps at cvsnt.org about a month ago.
