Microsoft Visual C++ Runtime Library - Debug Assertion Failed!

Running an application in a debug environment throws the following assertion message.

---------------------------
Microsoft Visual C++ Runtime Library
---------------------------
Debug Assertion Failed!

Program: x:\test\myapp.exe
File: minkernel\crts\ucrt\src\appcrt\heap\debug_heap.cpp
Line: 996

Expression: __acrt_first_block == header

For information on how your program can cause an assertion
failure, see the Visual C++ documentation on asserts.

(Press Retry to debug the application)

---------------------------
Abort   Retry   Ignore   
---------------------------

In my specific case, this was caused by a string created in the heap by a DLL and freed in the executable.  The DLL was built using /MDd [Configuration Properties | C/C++ | Code Generation | Runtime Library = Multi-threaded Debug DLL (/MDd)] and the executable was built /MTd with MFC as static library [Configuration Properties | C/C++ | Code Generation | Runtime Library = Multi-thread Debug (/MTd)]/[Configuration Properties | Advanced | Use of MFC = Use MFC in a Static Library]. 

The fix/workaround is to change the executable to use MFC as a shared library [Configuration Properties | Advanced | Use of MFC = Use MFC in a Shared DLL]

//end

Error! Could not locate dkms.conf file install VirtualBox 4.1.8 on Ubuntu 11.10

All other packages installed properly except that VirtualBox installation was complaining about missing dkms.conf file, see error message below. $: sudo /etc/init.d/vboxdrv setup * Stopping VirtualBox kernel modules [ OK ] * Uninstalling old VirtualBox DKMS kernel modules Error! Could not locate dkms.conf file. File: does not exist. [ OK ] * Trying to register the VirtualBox kernel modules using DKMS [ OK ] * Starting VirtualBox kernel modules [ OK ] Though it looks like installation was fine but I am concerned about its effects to VirtualBox functionality. To fix this, do: $: cd /var/lib/dkms/vboxhost $: sudo rm -r 4.1.4 $: sudo /etc/init.d/vboxdrv setup Of course you have to re

The following add-ins could not be started MonoDevelop.GnomePlatform

By
Installing MonoDevelop in OpenSUSE 12.2 from its repository was very easy. When running it for the first time though I got the message: The following add-ins could not be started: The root of the trace shows MonoDevelop.GnomePlatform,2.8 A quick search shows that MonoDevelop depends on libgnomeui . This should have been part of dependencies when installing the application but well.... Below is the screen shot of the error message. References: http://software.1713.n2.nabble.com/MonoDevelop-and-openSUSE-12-1-td7462957.html [2013/04/09] - Same issue observed in OpenSUSE 12.3 and also the same fix. [2014/11/02] - Same issue observed in OpenSUSE 13.3, mondevelop 3.0.6 and the same fix.
