Description:
------------
The test Zend/tests/bug42143.phpt contains:
13 var_dump(log10(-1) == log(-1));
14 var_dump(log10(-1) != log10(-1));
On Linux, that test works, because the logarithm of -1 returns NAN as expected.
On Solaris the log returns -INF and that part of the test fails. This behavior
is allowed by the specifications: See in
http://pubs.opengroup.org/onlinepubs/9699919799/functions/log.html
"For finite values of x that are less than 0 ..., a domain error shall occur,
and either a NaN (if supported), or an implementation-defined value shall be
returned."
Since there are a lot of other but similar tests in Zend/tests/bug42143.phpt, I
suggest to drop these two lines.
See attached patch.
