4b3: split(): bad regular expression for split()

Using it on Solaris-2.6 Sparc. I used the sample from the online manual: <? $date = "04/30/1973"; // Delimiters may be slash, dot, or hyphen list( $month, $day, $year ) = split( '[/.-]', $date ); echo "Month: $month; Day: $day; Year: $year<br>\n"; ?> And I get: Warning: bad regular expression for split() in /opt/whalemail/apache/htdocs/myproject/test/date.php on line 3 Month: ; Day: ; Year: I played around with it and got it to fail without returning any output, sometimes after hanging for quite a few seconds. I saw messages like the following in the logs: [Fri Jan 28 12:14:17 2000] [notice] child pid 10582 exit signal Segmentation Fault (11) FATAL: emalloc(): Unable to allocate -1515870799 bytes FATAL: erealloc(): Unable to allocate 1515870818 bytes Other samples from the manual ``split(":", $passwd, 5)'' failed similarly, as did attempts to use ereg_replace() [presumably because it uses the same split() code?]
