Today, I finally decided myself to look into this long-standing well
known bug, and realized this bug is actually zlib related. You can
reproduce the exact same behaviour with the following code snippet :

#include <zlib.h>

int main(void) {
  gzFile fd;
  char buffer[256];
  fd = gzdopen(dup(0), "rb");
  while(gzread(fd, buffer, 256));
  gzclose(fd);
  return 0;
}

Test it with:

$ gcc -o test test.c -lz
$ ./test

I'm reassigning to zlib

Cheers,

Mike
