core dump during "make check" in 6.6.8 on SUSE linux

[wealthychef]

I got the following output, and am not sure what to make of it, when running make check on our SUSE linux machines. ImageMagick tells me to report this. It is dumping core during the "make check" phase. Stack trace and listing is below as well.
I'd like this to work properly as I'm installing it globally for many users and this test failure is disturbing of course, but my own tests by hand seem to show things are OK, in that the "convert" command translates between all the image formats I've tested.
Any help or advice would be appreciated.

that the exception was not caught indicates a test failure.  A properly
