.NET Forum / Languages / Managed C++ / November 2006Managed VC++ crashing in debug build caused memory leaks
Hi everyone, I was surprised to see memory leaks in our application when it crashed today. Basically, the code is written in C#, but with c# and C++ DLLS; its the latter (managed extensions) that cause the memory leaks (the new operator in crtdbg.h). Does the garbage collector not work in debug build for VC++? TIA Paul  Signature---- Home: http://www.paullee.com Woes: http://www.dr_paul_lee.btinternet.co.uk/auto.shtml By the way, this is using .NET framework 1.1 - we can't upgrade to 2 yet! > Hi everyone, > I was surprised to see memory leaks in our application when it crashed [quoted text clipped - 6 lines] > > Paul Signature---- Home: http://www.paullee.com Woes: http://www.dr_paul_lee.btinternet.co.uk/auto.shtml > By the way, this is using .NET framework 1.1 - we can't upgrade to 2 yet! > [quoted text clipped - 4 lines] >> operator in crtdbg.h).

This is distinguished a lot better in C++/CLI, but you said you're stuck with .NET 1.1 :( >> TIA >> >> Paul >> By the way, this is using .NET framework 1.1 - we can't upgrade to 2 yet! >> [quoted text clipped - 9 lines] > can also allocate from the native heap.

However, it looks like all objects are declared using __gc, so maybe the memory leaks are an artefact of compiling in debug mode only? It looks like all the dynamically allocated objects are decorated with the gc moniker. I don't like to contemplate this, but does the CLR/garbage collector not work properly in debug build? ---- Home: http://www.paullee.com Woes: http://www.dr_paul_lee.btinternet.co.uk/auto.shtml
