Segfault only occurs when pressing launch/debug button from vscode

Question

I am trying to use Allegro 5's native file dialog addon, but I am getting a seg fault. This issue only occurs if I press the debug or launch button from the bottom of vscode, or if I run it from the CMake/Launch terminal within vscode.

My app does not seg fault if I run it from the bash terminal.

I believe I am having any issue with the vscode-cmake-tools, but I just cannot figure out what.

I have boiled it down to the below code triggering a seg fault, the al_show_native_file_dialog() line is where it crashes.

#include <stdio.h>
#include <allegro5/allegro.h>
#include <allegro5/allegro_native_dialog.h>

int main()
{
   al_init();
   al_init_native_dialog_addon();

   ALLEGRO_DISPLAY *disp = al_create_display(800, 800);

   ALLEGRO_FILECHOOSER *fc = al_create_native_file_dialog(NULL, "Test", NULL, ALLEGRO_FILECHOOSER_FILE_MUST_EXIST);

   if (!fc || !disp) return 1;
   
   al_show_native_file_dialog(disp, fc);

   if (al_get_native_file_dialog_count(fc) > 0)
   {
      printf("%s\n", al_get_native_file_dialog_path(fc, 0));
   }

   al_destroy_native_file_dialog(fc);

   al_destroy_display(disp);

   return 0;
}

I've been told on the Allegro.cc forums that it can crash if I try to write to a protected location, but in this example it just opens a dialog showing your recent files.

I am posting here because it seems less like an Allegro issue (as it does work without issue running from the terminal), and more of a vscode problem I'm having.

Any ideas why it might crash when launching from one terminal and not the other?
