I'm trying to write and run some file IO code for ARM, but I encounter a
fatal error when trying to run this simple C program:
test.c:
```c
#include <stdio.h>
int main(int argc, char **argv)
{
FILE *input = fopen(argv[1], "rb");
if (input == NULL)
{
printf("Error reading file: %s\n", argv[1]);
return 1;
}
fseek(input, 0L, SEEK_END);
long int size = ftell(input);
fseek(input, 0L, SEEK_SET);
return 0;
}
```
Binary (test.arm) compiled using command: arm-linux-gnueabihf-gcc -static
-o test.arm -std=gnu99 test.c
Run output:
```

```
I can confirm that the `fopen()` call completes successfully. The `fseek`
and `ftell` functions incur the fatal failed writeBlob error.
A backtrace of the error is here:
