External Email - Use Caution

By crashing from the GUI do you mean that you when you try to navigate to open a file, e.g., $SUBJECTS_DIR/bert/mri/brain.mgz, using the freeview GUI Open-> pull down menu that you get the core dump listed below, but it works when your run “freeview $SUBJECTS_DIR/bert/mri/brain.mgz” from the command line in the terminal window?

The core dump shows a memory allocation error on MacOSX. Some postings indicate setting MallocNanoZone to zero before running your program/command can remedy this,

$ bash

$ export MallocNanoZone=0 && freeview

- but this may not work. I don’t see any other workarounds for this right now. I have not seen this error before with freeview on older versions of MacOS, so it may be related to running on MacOS 10.13.

Gkxgears seems to work fine
