pulp/0.2 segmentation fault during bfs init
Hi,
I've noticed that PuLP crashes every 10nth run or so when partitioning this toy graph: https://drive.google.com/file/d/1q3wk6sa904y8iXTDPombxZC0pfGnpyht/view?usp=sharing
with arguments: ./pulp wing_nodal_2.graph 16
on a machine with 16 cores / 32 threads.
Is there something wrong with the file format?
or is the graph too small for the given number of cores?
Thread 23 "pulp" received signal SIGSEGV, Segmentation fault.

xtrapulp/0.3/pulp_mm.h should be recovered
There will be compiling error (header file missing) without recovering xtrapulp/0.3/pulp_mm.h back
