[MINC-users] mincmorph/minc2 bug (with workaround)

[Jason Lerch]

Hi all,

it appears that there is a bug in mincmorph (and maybe not only 
mincmorph) if the following conditions are met:

* mincmorph linked against minc2 (I'm using a fairly recent CVS version)
* input volume larger than volume_io cache threshold.

This causes a segfault along with the message "copy_volume():  copying 
cached volumes not implemented."

The main point of this email is that, if anyone else encounters the same 
situation, and if your volumes are not truly huge, the segfault can be 
circumvented by disabling volume caching:

export VOLUME_CACHE_THRESHOLD=-1

Cheers,

Jason
