Right.  Fixed in svn revision 4816.

It is well known that old libcs segfault on this, although POSIX does
not require such a behaviopus (iirc, it is undefined).  This is the same
class of problems as with passing a negative value to isfoo() - glibc is
robust enough to work correctly but HPUX will always segfault.  Anyway,
it needs to be fixed as we aim for portable software.

Thanks,
