[Tinycc-devel] -b problem...

[pierre]

Hi,

I have an error when running with bound check enabled a very simple file:

/***************************************************************/

#include <stdlib.h>
#include <stdio.h>
#include <string.h>

char *func(char *str) {
  int len;
  char *res;

  len = strlen(str);
  res = malloc(len + 3 + 1); //
  sprintf(res, "%s %d", str, 24);
 return res;
}

int main(int argc, char **argv)
{
  char *str;
  int a[10];

  str = func("test str");
  printf(str);

  a[0] = 10;
  printf("end");

  return 0;

}

/***************************************************************/

If I launch

• tcc -I libtcc libtcc/libtcc.def -run test.c

I am getting:

• test str 24end
  

but if I launch:

• tcc -I libtcc libtcc/libtcc.def -b -g -run test.c

I am getting:

• test str 24Runtime error: access violation
  test.c:23: at 0000000000356111 main()
  

any idea of why?

thanks,

Pierre
