Description H.Habighorst 2010-09-08 17:14:08 UTC

Application: kdevelop (4.0.2 (using KDevPlatform 1.0.2))
KDE Platform Version: 4.5.1 (KDE 4.5.1)
Qt Version: 4.6.3
Operating System: Linux 2.6.35-gentoo-r5 x86_64
Distribution (Platform): Gentoo Packages

-- Information about the crash:
I was writing a simple PHP Project (PHP5/OOP), but kdevelop crashed after a few seconds.

When I run gdb in a console, I get the following additional output:

kdevelop(1737)/kdeui (kdelibs): No such XML file "/home/henning/.kde4/share/apps/kdevelop/katepartui.rc"

kdevelop(1737)/kdevelop (php support) Php::ContextBuilder::startVisiting: importing internalFunctions failed "/home/henning/php/ueb1.php" 

Program received signal SIGSEGV, Segmentation fault.

bla.php was just a simple file with following content (not my project, rather a dumb test file, but still crashes):

<?php
        $a = array ('a', 'b', 'c');
        var_dump($a);
        var_dump(array_flip($a));

?>

The crash can be reproduced every time.

Comment 1 Milian Wolff 2010-09-13 11:28:16 UTC

is this reproducible? If so please run kdevelop through valgrind and send me the output.

kdevelop --sessions => get HASH for your session

KDEV_SESSION={...hash...} valgrind --track-origins=yes kdevelop.bin

=> reproduce, save & send us the log

valgrind log

Comment 3 H.Habighorst 2010-09-14 21:25:26 UTC

I don't get the same error now.

I've deleted the .kdevduchain directory .

The valgrind log is related to this gdb output:
