hi,
it took some time to isolate the problem, but here is the
testcase. the segfault is not triggered if PHP was compiled --enable-debug version, in
which case it complains
that it "Cannot use scalar value as an array".
<?php
header("Content-type: text/plain");
$arr[data] = "scalar";
for ($i=0;$i < 200; $i++) {
print $i."n";
// trying to use scalar value as an array
$arr[data][entries][] = array();
}
?>
i hope this helps.
regards,
lukas

hi,
below is the backtrace of the SEGFAULT.
i can reproduce in 100% of the cases by commenting in the one line
$this->attributes[data][entries][$zone][] = $entry;
or
$this->attributes[data][entries][$zone] = array();
$zone is a string
$entry is an array.
these are perfectly okay and work. but in the project i'm working on,
the code-path leading to these statements screws something up.
these lines are 2 nested while loops, and the segfault happens (always)
after the 3rd iteration of the inner loop.
i was not yet able to extract a (short) script to reproduce the problem,
but i will continue trying to create one...
regards,
-lukas
