Compilation fails: relocation truncated to fit: R_X86_64_32S against symbol... #16
Description
I am having problems trying to build the SHMEM port of the ISx benchmark on our Cray XC40 using PrgEnv-gnu (GCC 6.3.0). The error I get is:

I assume this is due to the large static array my_bucket_keys defined in isx.c so I tried to compile with -mcmodel=large, which only shifts the problem to some PMI function, so compilation still fails.
The MPI version of ISx builds just fine. Is this a known problem? Could it be a system configuration issue? Any help is much appreciated.
