Problems with gcc-3.1 -O2 on Solaris
Sat, 3 Aug 2002 19:04:21 +0100 (BST)
I've been having problems with gcc-3.1 and R-devel on one of our Solaris 7
systems (not the one I usually use). We have seen a report of
this before (Chuck Berry, 17 July 2002).
The symptom is that make check fails with var(1) being NaN not NA. The
underlying cause is that as.double(NA) is NaN.
It can be solved by compiling arithmetic.c without -O2.
Another installation with a single-processor UltraSparc 1 works correctly.
My guess is that gcc-3.1 and multiprocessor/Sparc IIIs are not mixing.
