Map template with unnamed layers

[Koji Ueda]

Hi list,

Excuse me if this is a known bug.

I recently updated my MapServer from 4.0 to 4.4.1.
It, however, caused a memory access violation error when I tried to use it in query mode (i.e. mode=nquery).
The map mode (mode=map) worked fine with no problem.

After struggling with this problem for a couple of hours,
I finally found out that LAYERs with no NAME tag caused this error.
I don't know if there was a specification change which specified the NAME tag as a requirement for LAYERs.
But it would be better if it could print a warning message instead of halting.

FYI, the first location mapserver fails is:

maptemplate.c line 2245
 strlcat(repstr, msObj->Map->layers[i].name, sizeof(repstr));
in the function processLine()

Here, msObj->Map->layers[i].name is NULL when the NAME is not specified for the LAYER.

Best Regards,
