Date: Wed, 26 Dec 2001 13:21:39 +0100 [thread overview]
Message-ID: <000901c18e07$e2877d10$010411ac@local> (raw)
The old code evaluates addr once, your new code evaluates it twice.
Have you tried an inline function instead of a macro?
linux/fs/binfmt_elf.c contains a few lines that probably break if 'addr' is evaluated twice:
<<<<<<<
argv = (elf_caddr_t *) sp;
if (!ibcs) {
__put_user((elf_addr_t)(unsigned long) envp,--sp);
__put_user((elf_addr_t)(unsigned long) argv,--sp);
}
