how to debug a possible problem with (rcs)merge

[Raghuram Devarakonda]

Hi,

In one particular case, rcsmerge does not report a conflict when it 
probably should. I am not sure if I can send out the actual files in bug 
report but I am investigating if there is anyway I can recreate the bug 
with some other dummy files. In the meanwhile, are there any special 
debugging procedures you suggest to use in analyzing the issue?

A brief description of the problem is as follows:

###############
$ diff file.1.54 file.1.55
<some other hunks>
....
1850a1857,1859
>             finally {
>                         ss.destroyNDMPSession();
>                 }
1851a1861
>

$ diff file.1.54 file

1850a1851
>           finally { //I3429XXX
##################

Since the added line at "1850" is conflicting, I thought that the 
following merge would report conflicts.

$ merge file.1.55 file.1.54 file

but it doesn't. Instead, it adds the line "finally { //I3429XXX" after 
the finally clause in 1.55 so that the end result looks like:

#############
             finally {
                         ss.destroyNDMPSession();
                 }
                finally { //I3429XXX

################

Am I missing something here? I am sorry if the report is sketchy but any 
help is appreciated. BTW, I also tried to use rcsmerge which gave the 
same result.

Thanks,
Raghu.
