Description Cassiano Leal 2010-06-25 16:27:52 UTC

Version:           4.0.0 (using KDE 4.4.4) 
OS:                Linux

kdevelop crashes while trying to parse a PHP project.

From the beginning of the parsing, gdb throws lots of error messages like these:

Reproducible: Always

Steps to Reproduce:
Nothing special. I'm not sure which file it was trying to parse when the error happened as there's not much verbosity in the parser (could be a wishlist, maybe!)

Comment 1 Milian Wolff 2010-06-28 20:25:04 UTC

Can you please provide me with the project so I can try to find the bug? The information here is not enough for that.

If you cannot do that, please do this instead (assuming you install kdevelop from git):

1) kdebugdialog -> enable php area
2) /path/to/build-folder-from-kdevplatform/util/duchainify/duchainify --verbose /path/to/your/php-project

and paste me the output of the last command.

Thanks

PS: for future bug reports, please install debug symbols for the PHP plugin.

Comment 2 Cassiano Leal 2010-07-06 16:58:34 UTC

While trying to compile kdevelop4 I get this message:


-- Found automoc4: /usr/bin/automoc4
CMake Error at /usr/share/cmake-2.8/Modules/FindPackageHandleStandardArgs.cmake:70 (MESSAGE):
  Could NOT find KDE4Workspace (missing: KDE4Workspace_CONFIG)

-- Configuring incomplete, errors occurred!

kdevplatform built and installed fine.

I am using Debian packages for everything here.

Comment 3 Cassiano Leal 2010-07-06 18:46:36 UTC

And sorry, but I can't provide you with the project since it's actually a proprietary software.

I couldn't find debugging symbols for the php plugin in the Debian repos.

Comment 4 Milian Wolff 2010-07-06 18:51:37 UTC

as it says, you need kdebase-workspace-dev packages.

Comment 5 Cassiano Leal 2010-07-06 21:26:09 UTC

Here are the last lines of duchainify up to the segfault (I have substituted the actual paths and file names):

duchainify(21670)/kdevplatform (language) KDevelop::BackgroundParserPrivate::parseDocumentsInternal: creating parse-job KUrl("file:///home/cassiano/path_to_file/SomeFile1.js") new count of active parse-jobs: 1

These are the contents of the file that has caused the segfault:


<?php
$sSignatures = <<<END_OF_SIGNATURE

And then it goes on with this binary blob until it reaches EOF.
