[C2M] Wrong initialization of struct's string fields

[edubart]

The following:

#include <stdio.h>
struct Boo { char data[5]; };
struct Boo boo = {"test"};
int main(int argc, char **argv) {
  puts(boo.data);
  return 0;
}

Outputs:

tests/bug1.c:3:19: warning -- assigning pointer without cast to integer
����U

It is expected as in GCC/Clang to print test, but it prints random data, because looks like it's wrongly assigning a pointer instead of initializing the struct.

PS: I was trying this project, mainly because I'm working in other language that already compiles to C, and I found this project promising as it's minimal and can compile C very fast. During my tests I found this issue.

Thank you for reporting this. I reproduced the problem. It looks c2m is trying to assign pointer to the string to the first element of the data. That is why this warning.

I'll work on it and probably the fix will be available on the next week. Unfortunately, C2M code for initialization in C is very complicated despite I already rewrote the code once.

I've just fixed it. The fix is in the repository.

Thanks, it works!
