------- Comment #1 from fxcoudert at gcc dot gnu dot org 2007-10-01 13:13 -------
Can you compile and run the following C test code? (gcc -std=c99, or the system
compiler)
#include <math.h>
#include <stdio.h>
int main (void)
{
printf ("%ld %ld %ld\n", lround (nextafter(0.5,-9.0)), lround (0.5), lround
(nextafter(0.5,9.0)));
}
It should print "0 1 1". If it prints "1 1 1", then your system libm has a bug.
(HP-UX is not alone there, as we already discovered such a problem in AIX and
powerpc-glibc, see PR33271). In that case, you might want to file a bug-report
to HP, and I will xfail the testcase on hppa-hpux.
