guile 2.0.11 make check failure for ppc architecture on opensuse 13.2

details of the log is available at:

There are two failing tests:
[ 1223s] FAIL: fractions.test: fractions: (eqv? (expt 2 1/2) (sqrt 2))
[ 1223s] FAIL: fractions.test: fractions: (eqv? (expt 2.0 1/2) (sqrt 2))

I have a guest on which I am able to recreate the problem,
but I do not know anything about guile to do investigation of the problem.

any suggestions ?

Sorry for the 15 month delay!  Our bad.  On the other hand we're finally
about to cut a 2.0.12 so it would be nice to fix this.  Can you still
find this condition?  If so can you run Guile and type these expressions
at the console:

(expt 2 1/2)
(expt 2.0 1/2)
(sqrt 2)

and attach the log of what you type and what Guile says in response?



The bugzilla should probably be closed now,
because since then it seems that problem disapeared.
If I do the manual tests as suggested there is no differences in expressions 
outputs as reported below.
