Well, it doesn't seem to show itself under 5.3.8 on the Linux server, so maybe
this was fixed and I just missed the report. Since my original report, I've had
several similar cases that happened somewhat randomly under 5.3.6, so I'll just
keep an eye out and if I get something that's reproducible under the latest
version, I'll file another bug. In the mean time, you can close this bug.
Thanks for your time.

Please try using this snapshot:

Hi, I still can not reproduce with your data.csv, could you try with the
5.3-trunk?

laruence@: I just caught that you stated your test file had 1005 lines. I'm not
sure if you misread what I wrote or if you mistyped what you tested, but the
test file I used was 10005 lines - you're off by an order of magnitude.
I uploaded my file to Dropbox. You can grab it here:
<http://dl.dropbox.com/u/9434155/data.csv>
If you're able to grab it and attach it to the bug or make it available
someplace more permanent, that would be great.

FWIW, I just reproduced it on a Linux server running 5.3.4. I'm working on
getting
a backtrace, but I need to build a debug version of PHP first.

Thank you for this bug report. To properly diagnose the problem, we
need a backtrace to see what is happening behind the scenes. To
find out how to generate a backtrace, please read
http://bugs.php.net/bugs-generating-backtrace.php for *NIX and
http://bugs.php.net/bugs-generating-backtrace-win32.php for Win32
Once you have generated a backtrace, please submit it to this bug
report and change the status back to "Open". Thank you for helping
us make PHP better.
I can not reproduce it with a test csv file(1005 line, 13 cloumns) with 5.3
trunk

Hmm, I don't see how to upload reproduction scripts. The script is below; I'll
leave the data
file to the tester. I created a simple CSV file that had 10,005 lines of 13
columns each, where
the value of every column is the alphabet. It included one trailing blank line
and used CRLF line
endings.
Here's the script:
<?php
ini_set('display_errors', 1);
ini_set('error_reporting', E_ALL | E_STRICT);
class NmsObj {
static public function ImportData($whichOption) {
$fileObj = new SplFileObject('TestData.csv');
$fileObj->setFlags(SplFileObject::SKIP_EMPTY |
SplFileObject::DROP_NEW_LINE |
SplFileObject::READ_CSV);
$return = array();
foreach ($fileObj as $oneLine) {
$return[] = new stdClass();
} //foreach
switch ($whichOption) {
case 1:
$return = array_slice($return, 0, 9999);
$result = SplFixedArray::fromArray($return);
//we get here
return $result;
break;
case 2:
$return = array_slice($return, 0, 10000);
$result = SplFixedArray::fromArray($return);
//we won't get here - get "Segmentation fault:
11"
return $result;
break;
} //switch
} //ImportData
} //NmsObj
//$dataSet1 = NmsObj::ImportData(1);
$dataSet1 = NmsObj::ImportData(2);
echo "Done!\n";
?>
