Hi,

thanks for testing!

Ok, from the file system paths, this looks like 64bit Gentoo Linux.

Could you apply the attached patch and report the result for this test
again? Just pass "--no-cpp builtin_abs" to the test runner.

The test was originally written this way because the actual values change
depending on the system they run on, but it would still be good to see them
in the output in case of a failure.

Since you mentioned your recent GCC version, do you see any C compiler
warnings in the output of this particular test (i.e. during the actual test
run, not in the final summary)? Maybe with "-Wall" in your CFLAGS?
