Exception 0xC0000005 while loading debugee in eclipse. #96929

Hello!

I'm trying to setup a "debug session" for .exe file in eclipse (Eclipse Version: 2024-06 (4.32.0)). I'm using "custom toolchain" for building .exe in eclipse/cdt. This "custom toolchain" involves Microsoft Visual Studio's (2019 / c++17) "cl.exe / link.exe"

I have installed the "lldb debugger" via https://github.com/mstorsjo/llvm-mingw/releases this is the version to be installed: https://github.com/mstorsjo/llvm-mingw/releases/tag/20240619 in particular: https://github.com/mstorsjo/llvm-mingw/releases/download/20240619/llvm-mingw-20240619-msvcrt-x86_64.zip

So ... When launching the debug session in eclipse for my application (that uses third-party dll's) - I got the following stacktrace: 

Exception Code: 0xC0000005

Some additional comments from me:

It looks like that if "lldb debugger" can not find ".pdb" file from .exe OR one of the "custom *.dll" dependent files - it throws the "Exception Code: 0xC0000005" somewhere in :

#0 0x00007ffe5841a48a llvm::pdb::GlobalsStream::findRecordsByName(llvm::StringRef, llvm::pdb::SymbolStream const&) const (D:\llvm\llvm-mingw-20240619-msvcrt-x86_64�in\libLLVM-18.dll+0x1efa48a)
