[R] R error in make check

[Prof Brian Ripley]

You should ask this on R-devel, and tell them exactly what compilers you 
used.  See the posting guide: this falls under

'Questions likely to prompt discussion unintelligible to non-programmers 
should go to to R-devel.'

But yes, it is something to worry about and it looks as if your compiler 
generated incorrect code.  The 'R Installation and Administration Guide' 
has things to say about what that compiler appears to be, and you seem 
not to have followed its advice.
