I have a native DLL that is a plug-in to a different application (one that I have essentially zero control of). Everything works just great until I link with an additional .lib file (links my DLL to another DLL named ABQSMABasCoreUtils.dll). This file contains some additional API from the parent application that I would like to utilize. I haven't even written any code to use any of the functions exported but just linking in this new DLL is causing problems. Specifically I get the following error when I attempt to run the program:

The application failed to initialize properly (0xc0000025). Clock on OK to terminate the application.

I believe I have read somewhere that this is typically due to a DllMain function returning FALSE. Also, the following message is written to the standard output:

ERROR: Memory allocation attempted before component initialization

I am almost 100% sure this error message is coming from the application and is not some type of Windows error.

Looking into this a little more (aka flailing around and flipping every switch I know of) I linked with /MAP turned on and found this in the resulting .map file:

 0001:000af220       ??3@YAXPEAX@Z              00000001800b0220 f   ABQSMABasCoreUtils_import:ABQSMABasCoreUtils.dll
 0001:000af226       ??2@YAPEAX_K@Z             00000001800b0226 f   ABQSMABasCoreUtils_import:ABQSMABasCoreUtils.dll
 0001:000af22c       ??_U@YAPEAX_K@Z            00000001800b022c f   ABQSMABasCoreUtils_import:ABQSMABasCoreUtils.dll
 0001:000af232       ??_V@YAXPEAX@Z             00000001800b0232 f   ABQSMABasCoreUtils_import:ABQSMABasCoreUtils.dll

If I undecorate those names using "undname" they give the following (same order):

void __cdecl operator delete(void * __ptr64)
void * __ptr64 __cdecl operator new(unsigned __int64)
void * __ptr64 __cdecl operator new[](unsigned __int64)
void __cdecl operator delete[](void * __ptr64)

I am not sure I understand how anything from ABQSMABasCoreUtils.dll can exist within this .map file or why my DLL is even attempting to load ABQSMABasCoreUtils.dll if I don't have any code that references this DLL. Can anyone help me put this information together and find out why this isn't working? For what it's worth I have confirmed via "dumpbin" that the parent application imports the same DLL (ABQSMABasCoreUtils.dll), so it is being loaded no matter what. I have also tried delay loading this DLL in my DLL but that did not change the results.
