Didn't display warning message when attempt to debug mismatched core and application

Internal bug id: 245741

Configuration

Ubuntu14 x64

Install latest verson of vscode and cppdebug extension.

Repro:

1. Compile following C++ code with x64 by default: g++ -g main.cpp - o a.out

int main()
{
int i=0;

 i=i/i;
 return 0;  

}

2. Compile the same code with x86: g++ -g -m32 main.cpp -o a.out-x86

3. Run the x64 program "a.out" and collect the core dump

4. Launch vscode by updating "program" and "coreDumpPath" as following:

5. F5

Here is the launch.json file:

{

..
"configurations": [
{
..
"targetArchitecture": "x64",
"program": "${workspaceRoot}/a.out-x86",
"args": [],
"stopAtEntry": false,
"coreDumpPath":"${workspaceRoot}/core",
"cwd": "${workspaceRoot}",
"environment": []

....
}
]
}

Observe:

There is no any message displayed in the debug console, this is difficult for customers to identify what the problem here if they happen to debug the mismatched core dump and application.

Attached log in attachment.

Investigation:

I try to debug the same scenario in gdb, it can at least prompt message like “warning: core file may not match specified executable file … warning: Selected architecture i386 is not compatible with reported target architecture i386:x86-64”

Inizia riproducendo la discrepanza con i comandi di compilazione x64 e x86 forniti e la configurazione launch.json, quindi ispeziona la console di debug durante l'avvio con F5. Traccia il modo in cui l'estensione gestisce coreDumpPath e l'architettura dell'eseguibile. Il lavoro è completato quando viene visualizzato un avviso chiaro se il core dump e l'applicazione non corrispondono, comparabile all'avviso gdb segnalato.
