Troubleshooting target program crash

[martty]

Hey, thanks for this great library! I am having trouble making it work though.
Here is what I tried:

• get the blink repo
• build blink x64 Debug (Microsoft (R) C/C++ Optimizing Compiler Version 19.16.27012.6 for x64)
• create target directory & cd there
• create test.cpp with:

#include <iostream>
void fn();
int main() {
	while (true) {
		fn();
	}
}

using std::cout; using std::endl;
void fn() {
	cout << "Hello World" << endl;
}

• compile test.cpp in a VS console with cl.exe /Z7 /Od /MDd /nologo /EHsc /std:c++latest test.cpp

• cd back to blink root

• launch blink with test.exe (bin\x64\Debug\blink.exe target\test.exe) in VS console
  output:
  Launching in target application ...
  Entry point was written to address 000000013F1A0000
  Reading PE import directory ...

  Found program debug database: C:\dev\blink\target\test.pdb
  Found source file: c:\dev\blink\target\test.cpp
  Starting compiler process ...
  Started process with PID 31796
  Starting file system watcher for 'c:\dev\blink\target' ...

• change output string in test.cpp to something else & save
  output:
  Detected modification to: c:\dev\blink\target\test.cpp
  Finished compiling "c:\dev\blink\target\test.obj" with code 0.
  Successfully linked object file into executable image.
  Detected modification to: c:\dev\blink\target\test.cpp
  The target application has exited with code 3221225501.

• the test.exe program crashes

• the additional change in blink was that I disabled commandline detection from the .obj file, as that didn't work, so the commandline used to build is the built-in (as described in Duplicate file modification notifications #13)

Use /ZI instead of /Z7 for command-line detection. I'll look into the crash, seems to be some CRT state getting corrupted.

[Trass3r]

Is /ZI required or could the implied /FC be enough?

[crosire]

/FC has no impact on the debug data stored in the object files (it only affects display in the command-line output), and that's what blink needs to determine the compiler command-line. So for that to work /ZI is required.
