Hello list,

I can't seem to get attaching files to work (Roundcube 1.0.1, Gentoo Linux, Apache 2.4.9, PHP 5.5.12). Whenever I click "attach a file", select a file and then click "upload", Apache logs messages like these:

[core:notice] [pid 9155:tid 140489408571264] AH00052: child pid 9482 exit signal Aborted (6) [core:notice] [pid 9155:tid 140489408571264] AH00052: child pid 9493 exit signal Aborted (6) *** Error in `/usr/sbin/apache2': free(): invalid pointer: 0x00007fc60035f9a8 ***

I made sure that $config['temp_dir'] points to a directory writeable by the Apache user. PHP settings ensure that file uploads are allowed. Roundcube reports

file_uploads: OK session.auto_start: OK zend.ze1_compatibility_mode: OK mbstring.func_overload: OK suhosin.session.encrypt: OK magic_quotes_runtime: OK magic_quotes_sybase: OK

I wonder how to better debug this problem to figure out what I am doing wrong here. Can you guys help me with this?
