I'am using PHP 5 with Fedora 7.

Scenario: 1.) Open SOAP connection to vboxwebsrv with SOAPClient() 2.) Call IWebsessionManager_logon() 3.) Call IVirtualBox_createMachine() 4.) Call IVirtualBox_openVirtualDiskImage() 5.) Call IVirtualBox_registerHardDisk() 6.) Call IMachine_attachHardDisk()

Attachment contain gdb output. thanks.

This looks like a buffer overrun somewhere. The pointers/object references in the last libstdc++ method calls are simply invalid. It would help greatly hunting this down if you could provide a standalone program which reproduces this bug, it'd save much debug time creating a testcase first. Worst case would be that my testcase would work fine and yours still wouldn't.

Crash was caused by a NULL error message string, which apparently wasn't liked by the text conversions.
