They work fine when tested against programs compiled using MinGW. However, I'm trying to make calls on these DLLs from within .NET applications. This works fine in many cases, and I have no problems with stability. However, when installed on certain machines and when running some applications I randomly get the following error from .NET.

It seems to occur when the DLL is being loaded initially when the app is starting and before anything in the DLL even gets called. I've checked permissions, dependencies and nothing seems to consistently fix the problem.
