Hi, its weird that I got different output from VIPs using 1 thread and 2 threads, as follows:

 > export IM_CONCURRENCY=1
 > vips im_benchmark ../data/bigben_2662x5500.v output1.v
...
> export IM_CONCURRENCY=2
> vips im_benchmark ../data/bigben_2662x5500.v output2.v
> diff output1.v output2.v 
Binary files output1.v and output2.v differ

any ideas?

cheers,
justin
