 OK, I'm embarrassed.  I updated my 3.1 tree yesterday and built and ran
 200.sixtrack and 254.gap; 200.sixtrack built and ran fine, so I assumed
 that I had picked up Jakub's patch, but it turns out I didn't.  Today I
 updated the tree again, verified that his patch is there, and both tests
 work fine.  Sorry for the confusion, PR 5968 is the same as PR 5891.
 
 I also saw runtime failures with 254.gap on i686-pc-linux.gnu, and with
 Jakub's fix for 5891 it now works fine.  I plan to continue building and
 running (with the small test input) SPEC CPU2000 benchmarks with a
 variety of optimization options and tracking down and reporting
 failures.
