Segmentation fault

[Thorifish]

Hi! I'm learning to use Gemini and having problems.
I downloaded data from #22 and when I run mpirun -n 1 ./sssp scale16_s.bin 65536 39, it returns

===================================================================================
= BAD TERMINATION OF ONE OF YOUR APPLICATION PROCESSES
= PID 13556 RUNNING AT siyuan-Alienware-m15-R6

= YOU CAN IGNORE THE BELOW CLEANUP MESSAGES

YOUR APPLICATION TERMINATED WITH THE EXIT STRING: Segmentation fault (signal 11)
This typically refers to a problem with your application.
Please see the FAQ page for debugging suggestions

Then I tried gdb:
(gdb) run scale16_s.bin 65536 39

Is there anyone can help me? Thanks a lot!

In my experience, there are two lines code may cause the segmentation fault：

1. nodestring does not end with '\0', it will cause the numa_parse_nodestring parse error.
   

   GeminiGraph/core/graph.hpp

   Line 173 in 170e7d3

   struct bitmask * nodemask = numa_parse_nodestring(nodestring);

2. dealloc_vertex_array func not return anything, so it should be void.
   

   GeminiGraph/core/graph.hpp

   Line 241 in 170e7d3

   T * dealloc_vertex_array(T * array) {

You can modify the code like this way. Sanzo00@f2be0a9 Hope it will help you.
