Imagemagick on RHEL 5 Power6 architecture

I'm having serious problems with a tiff preview creation and identify in Imagemagick on the IBM P-series Power6 archtecture, with a RHEL5 installation.

I do realize that the tiff might be bad (warnings on other ImageMagicks), however it is not giving me a seg fault on any other architecture, it is also working on Power 5 with RHEL4

The tiff can be found here, if anyone can help at all


The backtrace attached as code is from a simple "identify 156974.tif"

The Imagemagick dev team couldn't help, they can't test it on the power6/rhel5 combo since they are not millionaires ;)

Help or info to work around this is very much appreciated
