I ran AutoHotkey.exe in debug mode in Visual Studio + the script in debug mode in VSCode with vscode-autohotkey-debug (attach mode), and the stack before the crash was the following:
and the final error occurred in C:\Program Files (x86)\Windows Kits\10\Source\10.0.22621.0\ucrt\heap\debug_heap.cpp at line 359 _CrtMemBlockHeader* const header{static_cast<_CrtMemBlockHeader*>(HeapAlloc(__acrt_heap, 0, block_size))};
When I added the following lines here before the return
then the output was as follows:
I tried get => FileAppend("a", "*") instead of get => 1, but the line wasn't executed.
Hopefully this is of some help, and I'll try to debug this further when I get some free time...

Hopefully this is of some help, and I'll try to debug this further when I get some free time...
