(gdb) Previous Comments: --------------------------------------------------------------------------- [2001-03-11 16:21:25] sniper@php.net Try creating a GDB backtrace of that. 1. rm config.cache 2. Add --enable-debug to you php configure line 3. 'make clean ; make ; make install' 4. And same for apache (step 3.) 5. apachectl stop 6. gdb /path/to/httpd 7. (gdb) run -X 8. Then try that script I sent you. 9. When (if) it hangs, ctrl+c 10. (gdb) bt full 11. cut'n'paste that backtrace into this bug report. And do all this using the LATEST CVS snapshot. --Jani --------------------------------------------------------------------------- [2001-03-11 04:25:06] gerard@valencia.bc.ca I'm also getting the same problem with this script. Any script, even those that work on other systems, are giving problems on my system. --------------------------------------------------------------------------- [2001-03-10 20:04:10] sniper@php.net I can't reproduce this. Please try the following script. upload.php: <form action="upload.php" method="post" enctype="multipart/form-data" name="admin"> <input type="file" name="userfile"> <input type=submit> </form> <?php if(isset($userfile_size) && $userfile_size) { copy ($userfile, "/tmp/uploaded_file"); unlink($userfile); } ?> --------------------------------------------------------------------------- [2001-03-10 01:52:48] gerard@valencia.bc.ca I have compiled the CVS snapshot, with the same configure options as before, and the problem still exists. Have not compiled it with APC this time. I have copied php.ini-dist to /usr/local/lib/php.ini --------------------------------------------------------------------------- [2001-03-09 19:49:25] sniper@php.net 1. There is an entry for APC in your php.ini.. have you tried this without APC? 2. Please try the latest CVS snapshot from http://snaps.php.net/ --Jani --------------------------------------------------------------------------- The remainder of the comments for this report are too long.
