For benchmarking purposes, I've made a script that has 10000 clauses like
this:
$varN = <<<ENDN
var 0: $TEMPLATEN[var0]
<another 19 statements like this>
ENDN;
this script crashes after running for some time, with this backtrace:
Program received signal SIGSEGV, Segmentation fault.

BP_VAR_R));

Don't ask me to send the script, it's some megs long :) But here is the
meta-script that generates it:
<?
$tnum = 10000;
print "<?\n";
for($i=0;$i<$tnum;$i++) {
print "\$t$i = <<<TEND$i\nthis is a test $i\nvariable substitution\n";
for($j=1;$j<=20;$j++) {
print "var $j: \$TEMPLATE${i}[var$j]\n";
}
print "TEND$i;\n\n";
}
print "?>\n";
?>
