MPCs in SOL 105 cause segfault

[victorkemp]

Affects version 17.0.0, bb30cea, and my fix to issue #156

Output says:

       Deallocate GMN                
Program received signal SIGSEGV: Segmentation fault - invalid memory reference.
       Deallocate GOA                

       Deallocate MODE_NUM           
Backtrace for this error:
       Deallocate GEN_MASS
