I was testing the downsampling of EXR images to 8-bit PNG, and got this:
$ convert grey-gradient.exr -depth 8 out.png
Floating point exception
This is with a custom build of the SVN sources:
$ convert -version
Version: ImageMagick 6.3.5 07/01/07 Q64 HDRI http://www.imagemagick.org
Copyright: Copyright (C) 1999-2007 ImageMagick Studio LLC
Here is what GDB has to say about it:
----(cut here)----
$ gdb /path/to/convert
GNU gdb 6.4.90-debian
[...]
(gdb) r grey-gradient.exr -depth 8 out.png

I've attached the offending EXR file to this message.
