#include <string.h>

void testok(void) reentrant
{ char buff[20];

buff[0]=1;

strcpy(buff,"hello");

//ok: buff = "hello"

}

void testfail(void) reentrant
{ char buff[20];

buff[0]=1; buff[2]=2;

A failure of this would be far more convincing

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

void testok(void) reentrant
{
  char buff[20];
  buff[0]=1;
  strcpy(buff,"hello");
  puts(buff);
}

void testfail(void) reentrant
{
  char buff[20];
  buff[0]=1;
  buff[2]=2;
  strcpy(buff,"hello");
  puts(buff);
}

void main(void)
{
  testok();
  testfail();
}
