[Rd] different compilers and mzR build fails

[lejeczek]

I'm not sure if I should bother you team with this, 
apologies in case it's a bother.

I'm trying gcc 6.2.1 (from devtoolset-6) with R, everything 
seems to work just fine, except for mzR.
Here is failed build:

It did compile with 5.2.x (from devtoolset-4) and worked fine.
I'm hoping you guys could confirm it is purely compiler 
problem? Or point me(not a real programmer) a way to 
troubleshoot it properly?
many thanks,
L.
