Ah, I had never needed structs before, so have never been through  
this particular code path.  I have reproduced the problem with Matlab- 
generated matfiles, so now we know that it's not Octave-specific.

I removed the offending line that causes the crash and it's clear to  
me that there's a deeper issue.  I poked around for several minutes  
and didn't see the root of the problem.  Unfortunately, I don't have  
time to investigate any more deeply.  My thesis deadline looms.

Sorry I can't be of greater help.

Take care,
Nick
