metavelvet crashes at 'Starting pebble resolution...'

[vmon5589]

Either metavelvet crashes or freezes at this step. For error when freezing, see previous issue. Below is when it crashes due to a 'bus error':

I noticed that when compiling (using GCC-4-7 through GCC-4.8) there are several warnings:
./scaffold.h:21:9: warning: 'SSCAFFOLD_H' is used as a header guard here, followed by #define of a different macro [-Wheader-guard]
#ifndef SSCAFFOLD_H
^~~~~~~~~~~~~
./scaffold.h:22:9: note: 'SCAFFOLD_H' is defined here; did you mean 'SSCAFFOLD_H'?
#define SCAFFOLD_H

And finally, the final warning is:
