John, are those the only > hppa-hpux failures you see in the testsuite? Here are the failures that I see on hppa1.1-hp-hpu10.20: http://gcc.gnu.org/ml/gcc-testresults/2006-02/msg00635.html I don't see any failures at the moment on 4.1.0 on hppa2.0w-hp-hpux11.11. See http://gcc.gnu.org/ml/gcc-testresults/2006-02/msg00637.html hpux10.20 doesn't have scalbn and hpux11.x does, so that's one difference. The problem appears to be with the pow function called from the libgfortran version of scalbn. I had looked at the arguments in the call to pow in scalbn and they appear fine. However, the return contains a small rounding error. I didn't see the same rounding error when I wrote a little test program to try duplicate the effect. Possibly, the default rounding mode is somehow getting changed in the test program. scalbn is called several times before the error occurs. Dave -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=26253
