Hi,

I am using the tiff library version 3.9.4 on suse 11.2. There are programs I wrote many years ago using versions of libtiff from the mid 90s. I have been having trouble executing some of these programs. I recently got to use valgrind on one of my programs and got the following error messages.

==25472== Invalid read of size 4

==25472==    at 0x404CCEB: TIFFFindFieldInfo (tif_dirinfo.c:753)
==25472==    by 0x404A843: TIFFVGetField (tif_dir.c:971)
==25472==    by 0x404B33A: TIFFGetField (tif_dir.c:957)
==25472==    by 0x8048B3D: main (in

/home/rajat/Desktop/spots_program/spotsprogram) ==25472== Address 0x284 is not stack'd, malloc'd or (recently) free'd

Could anyone have an insight as to what kind of problems in the code could give rise to such errors?

thanks
