Ah, Watson - I deduce that you are using SpamAssassin 3.1, and have installed the recent OCR plugin which uses "gocr". Google shows a terrible wrapped representation of the raw TAR file with a link to the CVS server which is down at the moment, but taking a look at the source via http://jocr.sourceforge.net/ works See src/pgm2asc.c, line 548: 546 if (overflow==1){ 547 overflow|=2; 548 fprintf(stderr,"# Warning: frame_nn stack oerflow\n"); 549 } 550 free(buf); >From looking at the code, it looks like the image is too complex, and the code has a recursion check which fires when its internal stack (actually a buffer) gets too large, which is defined as a constant value of 1024. It appears from a very quick glance that it sets the flag when the memory allocation hits 1024 bytes, checks it at the end of the block and sets it to 2 if it was set to 1 and complains to stderr, and then does nothing else, so it can be safely ignored. In theory you could set it higher and recompile, or take out the warning... Re "oerflow" - spelling mistakes can be _so_ useful sometimes! Paul. -- No virus found in this outgoing message.
