Thread: CodeBlocks - my program crashes on file import (debugging).

Hi, im using CodeBlocks and have only changed code that follows on from this section. My program runs up to a importing all data and some outputs.
But if i run it in debug mode now. It crashes Codeblocks at file import.

The code i have.

Code:

int main(int argc, char* argv[]) {

    GJCType menu;

    char stringInput[MENU_INPUT + EXTRA_SPACE];
    int menuSelection = 0;
    char *ptr;

    systemInit(&menu);

    if (argc == 3) {
        loadData(&menu, argv[1], argv[2]);
    } else {
        fprintf(stderr, "File import incorrect should be menu.dat submenu.dat");
        exit(EXIT_FAILURE);
    }

Code:

int loadData(GJCType* menu, char* menuFile, char* submenuFile) {

    FILE *menuInput;
    FILE *submenuInput;
    char lineBuffer[MAX_LINE_LENGTH+1];

    int validation;

    printf("IMPORTING DATA... from Files\n");
    menuInput = fopen(menuFile, "r");  /* Crashes CodeBlocks here */
    submenuInput = fopen(submenuFile, "r");

Does it run outside the debugger?
Are you building it with debugging information included?

Runs when i do a 'Build and Run' but not with the Debugger.

Ok... so you're doing a debug build?

Yes.. it matters... release builds are not compatible with the debugger.

Debugger hangs at the line of code - menuInput = fopen(menuFile, "r"); following the debugger line by line.

Any chance that this could be caused by malloc at some point further in my code? Because that was the only thing i messed with before this happened.

Well... you could try investigating that... it's usually the last thing you mess with that causes the problems.
