Access Violation on program ending

[N0x61r0x6Bo0x6E]

Hey,

I'm getting access violation while main method ending execution. It's because probably unloading is not properly executed:

VOID DeviceFPGA_Close()
{
    PDEVICE_CONTEXT_FPGA ctx = (PDEVICE_CONTEXT_FPGA)ctxDeviceMain->hDevice;
    if(!ctx) { return; }
    if(ctx->dev.hFTDI) { ctx->dev.pfnFT_Close(ctx->dev.hFTDI); }
    if(ctx->dev.hModule) { FreeLibrary(ctx->dev.hModule); } <------ HERE IS ACCESS VIOLATION
    LocalFree(ctx->rxbuf.pb);
    LocalFree(ctx->txbuf.pb);
    LocalFree(ctx);
    ctxDeviceMain->hDevice = 0;
}

What can be wrong?

The flow looks like:

int main() {
    memory_manager * mm = new memory_manager("process-name.exe"); <-- here is the VMMDLL_Initialize

return 0; <--- after this, above access violation exception being thrown 
}

Thanks, that should not happen. I'll look into it. But with a bit of luck I'll do a major rewrite of these parts so hopefully it will go away. I hope it's not bothering you too much as-is right now since there may still be some time away before I'll be able to fix it.

does my new release just released resolve this issue?

Thanks for reporting this issue. I wish you good luck with your future DMA related ventures. Please let me know if you should stumble upon something in the future again.

Also, if you find PCILeech / MemProcFS useful please consider sponsoring the project here on Github. I see people purchasing hardware for hundreds of dollars (of which I receive absolutely zero dollars for - since I'm not related to hardware sales) just to be able to run my free open source software. Sponsorships go for as little as $2 and Github is matching it - a $2 sponsorship for you is a $4 sponsorship for me. Thank You :sparkling_heart:
