Mingw Gcc Windows 7 Reboot

[Thomas Dineen]

Gentle People:

     I have an unusual situation! For some time now I have been 
developing and application

using C with Mingw gcc. The application performs long overnight 
optimization runs,

sometimes running several days.

      The application crashes on Win7 (Read that causes Reboot on Win7) 
but runs fine on Win10!

Windows 7 - Mingw Gcc Build - Crashes Windows7

Windows 10 - Mingw Gcc Build - Works Great

Solaris - Gcc Build - Works Great

Redhat/CentOS- Gcc Build - Works Great

    I am aware of memory consumption or leak issues, and with 
significant amounts of effort have

fixed them in the architecture. The architecture relies heavily on 
linked lists and I am well aware of

freeing or recycling unneeded lists to control memory leaks. I have 
verified this with observation of the

Resource Monitor!

     Question 1: Has anyone else seen this type of bug?

     Question 2: How do I debug this given the fact that Win 7 crashes 
and takes gdb with it.
