The following program will crash when built with v2.04/cvs due to a free
nonallocate block assert failure.  Fails on Win2K and Win95.

You must not have the DJGPP environment variable set to have it fail 
(if set, it runs).  Evil.

Compiled with gcc -g env2.c -o env2.exe

#include <stdio.h>

extern char **environ;

int main (int argc, char **argv, char **envp)
{
  char *dummy_environ[1];

  malloc_debug(3);

  environ = dummy_environ;
  environ[0] = NULL;

  for (; *envp; envp++)
    putenv (*envp);

  while (*environ)
    puts (*environ++);

  return 0;
}
