godot-python gets heap corruption (Windows Application Verifier) error while starting up
I had a memory corruption problem in my app, so I tried turning on Application Verifier using Windows gflags (https://docs.microsoft.com/en-us/windows-hardware/drivers/debugger/gflags-overview) to see where the corruption was happening. But doing that shows a heap corruption issue (overwriting the end of a block) while starting python from godot.
This is with latest Godot 0f930f831, gdnative d8becfb, and godot-python 6518e25. Using Windows python 3.6.3 and Visual Studio 2015.
Here's a simple test project that shows it: godot-autoload-example.zip
To repro, either use gflags.exe and enable page heap or application verifier for godot.windows.tools.exe, or just set the registry key Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Image File Execution Options\godot.windows.tools.exe:
GlobalFlag: dword:0x02000000
PageHeapFlags: dword:0x3
Here's the error:
===========================================================
VERIFIER STOP 000000000000000F: pid 0x4EC4: corrupted suffix pattern
000002E424761000 : Heap handle
