Slightly modified testcase

This testcase is similar, but gives the error, I think it has the same cause,
might be helpful:
testcase.c: In function 'foo':
testcase.c:2:6: error: virtual use of statement not up-to-date
 void foo(int n, int nreps, float tdgefa, float tdgesl)
      ^
# .MEM_25 = VDEF <_7>
printf ("%f\n", _24);
testcase.c:2:6: internal compiler error: verify_ssa failed
