What steps will reproduce the problem?
1. Compile the attached program against r2997 and patches 254 + 447
2 Run the program with the attached 0.jp2 file. ./jp2tile 0.jp2
What is the expected output?
See the pgm. The first tile (upper right corner) is correct the other tiles
are wrong.
What version of the product are you using? On what operating system?
cvs r2997 + patches 254 + 447. If only r2997 also the first tile is bad
When running the program with valgrind there is an error about access of
an uninitialized variable. this might cause a problem.
