Mapscript/cloneMap/Processing

[Benedikt Rothe]

Hallo List

We are using MapScript/Java inside Tomcat.
We encountered a crash in webObj.cloneMap() when 
a PROCESSING-statement was used inside a Layer-Block.

My impression is, that there is a bug in mapcopy.c/msCopyLayer (?)

I think: After the line
      MS_COPYSTELEM(numprocessing);
and before the loop
      for (i = 0; i < dst->numprocessing; i++) {...}
a memory-allocation for dst->processing is missing.

I made a change:
  MS_COPYSTELEM(numprocessing);  //OLD
  // Allocating an initializing memory for processing-array.
  // Must be dst->numprocessing+1 to be 0-terminated.
  dst->processing = numprocessing ? 
                              (char*) 
calloc(dst->numprocessing+1,sizeof(char*)) : 
                              0;
  for (i = 0; i < dst->numprocessing; i++) {   //OLD
  ...

I hope this is helpful. Greetings
Benedikt Rothe
