this looks to be the same as #1313

it looks to me like the destructor for php3 fclose() is simply libc's fclose!

functions/file.c
    GLOBAL(le_fp) = register_list_destructors(fclose,NULL);
    GLOBAL(le_pp) = register_list_destructors(__pclose,NULL);

so i made it:
    GLOBAL(le_fp) = register_list_destructors(__fclose,NULL);
    GLOBAL(le_pp) = register_list_destructors(__pclose,NULL);

and added:
static void __fclose(FILE *fp)
{
TLS_VARS;
    fclose(fp);
}

that seems to fix it.  of course, i have no clue what TLS_VARS is all about .. just copied from __pclose up above =:)
