Memory allocation failed even if memory is not exhausted

[oyvind.eide]

I am running convert on a computer with the following settings for memory usage:

> convert -list resource
File Area Memory Map Disk
------------------------------------------------
192 64gb 48gb 256gb 4eb

The image USD_UIO_2713046.tif is 2584x3981 pixels. The following command is OK:

> convert -resize 2584x3981 USD_UIO_2713046.tif temp.jpg

But trying to resize to anything smaller gives a memory allocation failed error:

> convert -debug Resource -resize 1000x1000 USD_UIO_2713046.tif temp.jpg

There is plenty of memory and temp disc space free.

We tried your command with the latest release, 6.3.4-4, and it worked without complaint. In regards to memory, ImageMagick controls the amount of memory it consumes but has no control over any delegate library. Its possible the memory allocation exception occurs within the TIFF library.

Thank you for answering so quickly, I will try upgrading and see if that helps.
