Hi,

Thanks for your report.  After some testing, I believe the problem is specific
to the LTO option.  I think you are also correct to suspect the issue is
related to the switch from version 4.8 to 4.9 as the default GCC version.

Only after the switch to GCC version 4.9 do the following warnings appear.

/usr/local/bin/ar: regcomp.o: plugin needed to handle lto object
/usr/local/bin/ar: regerror.o: plugin needed to handle lto object
/usr/local/bin/ar: regexec.o: plugin needed to handle lto object
/usr/local/bin/ar: tre-ast.o: plugin needed to handle lto object
/usr/local/bin/ar: tre-compile.o: plugin needed to handle lto object
/usr/local/bin/ar: tre-match-approx.o: plugin needed to handle lto object
/usr/local/bin/ar: tre-match-backtrack.o: plugin needed to handle lto object
/usr/local/bin/ar: tre-match-parallel.o: plugin needed to handle lto object
/usr/local/bin/ar: tre-mem.o: plugin needed to handle lto object
/usr/local/bin/ar: tre-parse.o: plugin needed to handle lto object
/usr/local/bin/ar: tre-stack.o: plugin needed to handle lto object
/usr/local/bin/ar: xmalloc.o: plugin needed to handle lto object

I haven't found a solution yet, but hopefully will soon.
