[FIXED] 'Access violation' at 0x004a8b9c (optimizer thinks too much?)

I know the code is weird :-) It works when you do -DUSE_VAR or remove -O2.

Code Select Expand

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

static char foo[1024];

int main(int argc, char * argv[])
{
  size_t            n;
  char *            x;

  if (argc < 2)
    return -1;

  n = strlen(argv[1]);
  strcpy(foo, argv[1]);
 
#ifdef USE_VAR
  x = (n >= 4 && strcmp(&foo[n - 4], ".bar") == 0) ? &foo[n - 4] : &foo[n];
  strcpy(x, ".baz");
#else
  strcpy((n >= 4 && strcmp(&foo[n - 4], ".bar") == 0) ? &foo[n - 4] : &foo[n], ".baz");
#endif

  printf("Result: %s\n", foo);
  return 0;
}

It is Pelles ISO C Compiler, Version 7.00.9 from the latest 7.0 RC3.

Yes, yuck about the code -- but at least I can reproduce the problem...
