[Super-tux-devel] bug in cvs code

[Arkadiusz M. <ar...@pl...>]

Hi,

Bug:

lispreader.cpp: lisp_read_from_file() tries to open file and return FILE=20
handle but if it fails to open it doesn't exit with error and just pasess=20
NULL to calling functions.

Now we have
SpriteManager::load_resfile(const std::string& filename)
{
  lisp_object_t* cur =3D lisp_read_from_file(filename);

  if (strcmp(lisp_symbol(lisp_car(cur)), "supertux-resources") !=3D 0)
    return;
  cur =3D lisp_cdr(cur);

and nice segfault at lisp_car() since cur can be NULL.

=2D-=20
