[Insight-users] DeformableModelSimplexMesh segmentation fault

[Charlotte Curtis]

I seem to have terrible luck getting the sample applications to run.  This
time, I am trying to run DeformableModelSimplexMesh, and I have set
LIBGL_ALWAYS_INDIRECT to 1 (otherwise it crashes before it even starts).  I
can do everything following the directions of how_to_use.html up to "deform
mesh", at which point the seg fault happens.  If I run through gdb, I don't
get much info:

 Preprocessing DONE!...
 Iteration   0

Program received signal SIGSEGV, Segmentation fault.

This occurs both with my own dataset and with the VTK sample data
HeadMRVolume.  The header is:

NDims = 3
> DimSize = 48 62 42
> ElementSize = 4.000000e+000 4.000000e+000 4.000000e+000
> ElementSpacing = 4.000000e+000 4.000000e+000 4.000000e+000
> ElementType = MET_UCHAR
> ElementByteOrderMSB = False
> ElementDataFile = HeadMRVolume.raw


Any ideas?
